AB  - Stinging nettle (SN) is an extraordinary plant from the Urticaceae botanical family. It is well-known and widely used in food and folk medicine to treat different disorders and diseases. This article aimed to study the chemical composition of SN leaves extracts, i.e., polyphenolic compounds and vitamins B and C, because many studies ascribed high biological potency to these compounds and their significance in the human diet. Besides the chemical profile, the thermal properties of the extracts were studied. The results confirmed presence of many polyphenolic compounds and vitamins B and C. It also showed that the chemical profile closely correlated with the applied extraction technique. The thermal analysis showed that analyzed samples were thermally stable up to about 160 degrees C. Thermal degradation of samples UAE, MAE, and MAC took place in four steps, and sample SE in three steps. Altogether, results confirmed the presence of health-beneficial compounds in stinging nettle leaves and indicated the possible application of its extract in pharmaceutical and food industries as both a medicinal and food additive.

AB  - Stinging nettle (Urtica dioica L.) is one fantastic plant widely used in folk medicine, pharmacy, cosmetics, and food. This plant's popularity may be explained by its chemical composition, containing a wide range of compounds significant for human health and diet. This study aimed to investigate extracts of exhausted stinging nettle leaves after supercritical fluid extraction obtained using ultrasound and microwave techniques. Extracts were analyzed to obtain insight into the chemical composition and biological activity. These extracts were shown to be more potent than those of previously untreated leaves. The principal component analysis was applied as a pattern recognition tool to visualize the antioxidant capacity and cytotoxic activity of extract obtained from exhausted stinging nettle leaves. An artificial neural network model is presented for the prediction of the antioxidant activity of samples according to polyphenolic profile data, showing a suitable anticipation property (the r(2) value during the training cycle for output variables was 0.999).

AB  - Stinging nettle is annual plant from Urticaceae family used as food and medicine. Due to the nonsufficient data, this work aimed to isolate the bioactive compounds from the stinging nettle leaves by supercritical carbon dioxide. Extracts were analyzed and assessed for antioxidant and cytotoxic activities. Main fatty acids were alpha-linolenic (31.06-58.42 mg/g E), palmitic (9.17-13.12 mg/g E), and linoleic (10.93-16.51 mg/g E) acids. Chlorophylls (33.00-7365.11 mg/100 g E) and carotenoids (166.88-722.62 mg/100 g E) were also found in all samples. Four empirical kinetic equations were effectively utilized for kinetic modeling of supercritical fluid extraction. As per proper statistical features, empirical models show good concurrence with experimental data. The numerical modeling of a process is gainful to foresee the process conduct and furthermore extend the methodology from laboratory to industrial scales. The principal component analysis was used to visualize the fatty acids profile, antioxidant capacity, and cytotoxic activity of extract.

AB  - This study was primarily focused on the supercritical fluid extraction (SFE) of cherry seed oil and the optimization of the process using sequential extraction kinetics modeling and artificial neural networks (ANN). The SFE study was organized according to Box-Behnken design of experiment, with additional runs. Pressure, temperature and flow rate were chosen as independent variables. Five well known empirical kinetic models and three mass-transfer kinetics models based on the Sovova's solution of SFE equations were successfully applied for kinetics modeling. The developed mass-transfer models exhibited better fit of experimental data, according to the calculated statistical tests (R-2, SSE and AARD). The initial slope of the SFE curve was evaluated as an output variable in the ANN optimization. The obtained results suggested that it is advisable to lead SFE process at an increased pressure and CO2 flow rate with lower temperature and particle size values to reach a maximal initial slope.

AB  - Peppermint is widely used medicinal plant with distinguished bioactive potential, therefore, the aim of present work was to develop novel peppermint extracts with high activity by application of traditional and emerging separation techniques. Conventional hydrodistillation and microwave-assisted hydrodistillation (MWHD) were applied for recovery of essential oil (EO), while organic solvent extraction using Soxhlet apparatus, microwave-assisted and ultrasound-assisted process and supercritical fluid extraction (SFE) were applied for non-selective recovery of peppermint lipophilic extracts. Extracts were characterized in terms of terpenoids profile with special emphasis on content of major compounds (mentol, menthone, isomenthol and eucalyptol). Antioxidant activity (DPPH, ABTS, CUPRAC, FRAP, chelating and phosphomolybdenum assay) and enzyme-inhibitory assays (acetylcholinesterase, butyrylcholinesterase, tyrosinase, amylase and glucosidase inhibition) were used for screening of peppermint bioactivity. MWHD was recognized as alternative for traditional process in EO recovery, while SFE extracts were useful for green production of solvent-free peppermint extracts rich in terpenoids and other lipophilic bioactives.

AB  - The main goal of this study was to establish the chemical profile of Osage orange (Maclura pomifera) leaf extracts, obtained by conventional maceration technique, and to examine its antimicrobial activity. The identification and quantification of the extract compounds were done using ultra-high-performance liquid chromatography, with a diode array detector coupled with triple-quadrupole mass spectrometer and gas chromatography-mass spectrometry techniques. Thirty-one polyphenolic compounds were detected and identified in the ethanolic extracts, whereby 5-O-caffeoylquinic acid was found to be the dominant compound. Among other compounds, pentacosane and palmitic acid were the most abundant compounds in the dichloromethane extract. The preliminary antimicrobial activity screening shows that Gram-positive bacteria tend to be more sensitive to the investigated extracts. The highest antimicrobial activity was determined against Enterococcus faecalis ATCC 19433 and Listeria monocytogenes ATCC 35152. From these results, Osage orange leaves can be considered as plant material with significant antimicrobial properties.

AB  - Sage herbal dust generated as a by-product from filter-tea factory contains various bioactive compounds which secured its economic potential towards valorization of under-utilized stream. The aim of this work was to utilize sage herbal dust as raw material for the recovery of value-added product. Comparative evaluation of hydrodistillation (HD) and microwave-assisted hydrodistillation (MWHD) processes applied for isolation of sage herbal dust essential oil (EO) were applied for this purpose and EO yield varied from 0.50 to 1.90%. Distillation experiments performed at different levels of power and kinetics of EO recovery were monitored, while four empirical kinetic equations were successfully applied for modeling of process kinetics according to appropriate values of statistical parameters (R2 and AARD). GC-MS analysis was applied for chemical characterization of sage EOs, while DPPH assay was used to determine in vitro bioactivity and results suggested that power affected terpenoid profile and antioxidant activity in case of HD and MWHD. Thermal analysis of obtained EOs was utilized to establish correlation between thermal behavior and terpenoids profile. Results suggested that MWHD could provide excellent alternative for production of high-quality sage EO with high content of oxygenated terpenoids and adequate bioactivity.

AB  - Stinging nettle (Urtica dioica L.) is a perennial plant belonging to the Urticaceae family. Several studies have reported the presence of the different classes of chemical compounds, which expressed a beneficial effect on human health. Among them there are elements and minerals that are essential for the proper functioning of organism. Mineral occurrence requires analytical data about the content. For such purposes was developed and validated a method based on the optical emission spectroscopy coupled with inductively coupled plasma (ICP-OES). Minerals and elements were extracted using two conventional methods (Soxhlet and maceration) and two non-conventional (ultrasound- and microwave-assisted techniques). The extracts were analyzed resulting in high diversity in the composition. Non-conventional techniques showed better results, since those extracts possessed high content of the macroelements and iron as well, instead the toxic elements were found in trace amount

AB  - The effect of supercritical fluid extract of tomato pomace (TP) and essential oil of organic peppermint (PM) on pH, color, residual nitrite content, lipid oxidation (TBARS value) and total plate count (TPC) of cooked pork sausages produced with 50 mg/kg of sodium nitrite was investigated. Five batches were produced: T1: 100 mgkg of sodium nitrite; T2: 50 mg of sodium nitrite; T3: 50 mg of sodium nitrite and 0.150 mu L/g TP; T4: 50 mg of sodium nitrite, 0.075 mu L/g TP and 0.075 mu L/g PM; T5: 50 mg of sodium nitrite and 0.150 mu L/g PM. The lowest residual nitrite content and TBARS value were observed in treatment T4. The inclusion of TP increased redness of cooked pork sausages. TPC was the lowest in treatment T5. The results of this study showed that the addition of TP and PM enhanced quality of cooked sausages produced with reduced level of sodium nitrite.

Sequential extraction kinetic modelling and artificial neural networks (ANN) were used for this purpose. SFE was performed according to the broaden Box-Behnken experimental design with pressure, temperature and CO2 flow rate as independent variables, while the influence of particle size on extraction kinetics and adjustable model parameters was additionally evaluated. Five empirical kinetic equations and mass-transfer model proposed by Sovova were utilized for extraction kinetics modelling. According to appropriate statistical parameters (R-2, SSE and AARD), the mass-transfer model exhibited the best fit of experimental data. The initial mass-transfer rate of extraction curve was used as a response variable in ANN optimization. SFE should be performed at elevated pressure and CO2 flow rate, while temperature and particle size should be held at a lower level in order to achieve a maximal initial mass-transfer rate.

AB  - Essential oils (EOs) are aromatic oily liquids prepared from plant material. Many plants are rich in EOs, which usually consisted of different secondary metabolites such as terpenoids. The EOs or their components have been shown to exhibit antioxidant, antimicrobial, antiviral, antimycotic, antitoxigenic, antiparasitic and insecticidal properties, which is main reason for their ivenstigation. Coriander and sage essential oils, isolated by hydrodistillation, were analyzed using gas chromatography, differential scanning calorimetry and thermogravimetry techniques in order to correlate chemical composition and thermal behavior. Results showed that evaporation process of sage EO takes place in two steps, while coriander EO was evaporated in one step. The activation energy of the evaporation process of both EOs was in accordance to the evaporation enthalpy of dominant compounds in analyzed samples. The quantitative structure-retention relationship (QSRR) was employed to predict the retention time (RT) of essential oil compounds obtained by GC analysis, using five molecular descriptors selected by genetic algorithm. The selected descriptors were used as inputs of an artificial neural network (ANN), to build an RT predictive QSRR model. The coefficient of determination was 0.969, indicating that this model could be used for prediction of RT values for coriander and sage essential oil compounds.

AB  - The main goal of this research was to determine the relationship among chemical structure, bioactivity and temperature of chamomile during subcritical water extraction in isobaric conditions (45 bar) at seven different temperatures (65-210 degrees C). The influence of temperature on phenolic profiles was defined by UHPLC-HESI-MS/MS. The overall results indicate that the presence of conjugated double bonds, side chains, glucose moiety or ether moiety in molecules influence the efficiency of polyphenols' extraction in subcritical water. In terms of antioxidant activity, the extracts were the most active towards ABTS radicals (IC50 = 7.3-16.8 mu g/mL), whereby temperature of 150 degrees C was optimal. On the other hand, the extracts obtained at 115 degrees C showed highest cytotoxicity. Inhibition of alpha-amylase and alpha-glucosidase was the highest at 65 and 85 degrees C, i.e. 0.51 and 4.13 mmolAE/g, respectively. Activity against tyrosinase was the highest at 210 degrees C (17.92 mgKAE/g). The data showed that different non-phenolic compounds may also participate in bio-activities of the extracts.

SEO, SE1 and SE2 improved oxidative and microbial stability of fresh pork sausages. The addition of SEO and SE1 at concentration of 0.150 mu L/g affected the reduction of total Enterobacteriaeceae count to under 3 log cfu/g. Sausages produced with SE1 and SE2 had a higher scores for odor, flavor and overall acceptance compared to sausages treated with SEO and control sample. Therefore, the results of this paper revealed significant antioxidative and antimicrobial activity of SE1 and SE2, and consequently its high potential of utilization in processing of fresh pork sausages.

AB  - Stinging nettle is a perennial plant with significant biological activity and a long history of application in folk medicine and as food. Its activity is ascribed to its chemical composition. Its leaves contain different classes of compounds including fatty acids. This study deals with the isolation of fatty acids in stinging nettle leaves using a rapid extraction system for solid-liquid extraction (Soxtherm) with petroleum ether as the solvent. The obtained results indicate that the saturated fatty acids are more abundant than unsaturated fatty acids. The most abundant fatty acids are C12:0 (20.94%, 348.07 g g(-1)), C16:0 (18.57%, 309.06 g g(-1)), and C18:1 (13.16%, 219.44 g g(-1)), whereas the fatty acid with the lowest content is C17:1 (0.13%, 2.20 g g(-1)). Prior to analysis, the method is validated to obtain accurate and precise results. The limit of detection and limit of quantification are 0.012-0.038% and 1.67-7.03%, whereas the precision and accuracy are 83-126% and 1.67-7.03%, respectively. The validation parameters are >0.999, 0.011-0.032%, 0.012-0.038%, 1.67-7.03%, 83-126%, 0.22-5.24%, and 0.38-6.94% for linearity, limit of detection, limit of quantitation, precision, accuracy, inter-day precision, and intra-day precision, respectively, confirming the suitability of this method for fatty acid analysis.

AB  - Background: Lavatera thuringiaca L. is herbaceous perennial plant from Malvaceae family, which is known for its biological activity and richness in polyphenolic compounds. Despite this, the information regarding the biological activity and chemical profile is still insufficient. Purpose: Aim of this study was to investigate biological potential and chemical profile of Lavatera thuringiaca L., as well as influence of applied extraction technique on them. Study design and methods: Two conventional and four non-conventional extraction techniques were applied in order to obtain extracts rich in bioactive compound. Extracts were further tested for total phenolics, flavonoids, condensed tannins, gallotannins and anthocyanins contents using spectrophotometric assays. Polyphenolic profile was established using HPLC-DAD analysis. Biological activity was investigated regarding antioxidant, cytotoxic and antibacterial activities. Four antioxidant assays were applied as well as three different cell lines for cytotoxic and fifteen bacterial strain for antibacterial activity. Results and conclusion: Results showed that subcritical water extraction (SCW) dominated over the other extraction techniques, where SCW extract exhibited the highest biological activity. Study indicates that plant Lavatera thuringiaca L. may be used as a potential source of biologically compounds.

AB  - In the last few years, bioactive components or their extraction techniques are gaining special interest in scientific areas. In this framework, orange leaves were used for preparation of extracts with high content of biologically active compounds. To optimize the extraction process, three levels and three variables of Box-Behnken design with response surface methodology were applied. Investigated responses were the total phenolic content (TPC), 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical, cupric ion reducing antioxidant capacity (CUPRAC), and ferric reducing antioxidant power (FRAP). Independent variables were methanol concentration (10-90%), temperature (20-60 degrees C), and extraction time (60-180min). Experimentally obtained results were fit into a second-order polynomial model with multiple regression. Analysis of variance was used to estimate model fitness and determine optimal conditions for processing. Estimated optimal conditions were 90% methanolic solution, 60 degrees C and 180min using these parameters; the predicted values of investigated responses were 43.19mg GAE/g (GAE: gallic acid equivalents), 43.04mg TE/g (TE: trolox equivalents), 139.34 and 93.76mg TE/g for TPC, DPPH, CUPRAC, and FRAP, respectively. The obtained optimal conditions could be considered as an alternative strategy for developing novel functional products.

AB  - Fruits of Prunus cerasus L. (tart cherry) represent a significant source of health beneficial compounds and have been widely used in food industry. Despite that, other plant parts, such as twigs, have not been investigated. Aim of this study was to investigate chemical profile of twig extracts prepared from plant material of three cultivars. Wig extracts were prepared using maceration and Soxhlet extraction approaches, and investigated regarding phenolics (5.85-14.80 mg.l(-1)) and saccharides (123.38-339.46 g.l(-1)) concentrations using high performance liquid chromatography (HPLC) analysis. Total phenolics (99.34-139.77 g.kg(-1)), flavonoids (14.18-42.88 g.kg(-1)), anthocyanins (76.71-84.97 g.kg(-1)), condensed tannins (52.65-79.76 g.kg(-1)) and gallotannins (19.03-37.23 g.kg(-1)) contents were determined using spectrophotometric analysis. Biological activity was investigated using four antioxidant assays (total antioxidant capacity, 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, lipid peroxidation assay and hydroxyl radical-scavenging activity). Cytotoxic activity was assessed on three different cell lines (Hep2c, RD and L2OB), while antimicrobial activity was established on 15 bacterial strains. Obtained results confirmed the presence of health beneficial compounds in twigs and indicated the possibility of utilization as a secondary source of those compounds.

AB  - The study was designed to determine the relationship between chemical structure, bioactivity and pressure during the subcritical water extraction (SCW) of chamomile. Extraction was carried out at isothermal conditions (100 degrees C) at five different pressures (10, 30, 45, 60 and 90 bar). Twenty three polyphenolic compounds were identified in the extracts, whereby apigenin was found to be the dominant compound (61.53-1344.99 mg/kg). Results suggest that the lowest applied pressure has negligible effect on phenolic recovery from chamomile, but also the use of pressures above than 45 bar was proven as needlessly. By using in vitro assays, influence of pressure on antioxidant, cytotoxic and enzyme-inhibitory activities of the extracts was evaluated. Extracts obtained at 30, 45 and 60 bar exhibited stronger bioactivities than at 10 and 90 bar. It was concluded that pressure exert a significant influence on chemical composition of extracts, and thus on biological activity of chamomile extracts.

AB  - The present study aimed to evaluate chemical and biological potential of aronia stems for providing new raw material for food and pharmaceutical industries. Aqueous extracts of aronia stems were prepared by three different techniques (microwave-assisted, ultrasound-assisted and subcritical water extraction). For biological activities, antioxidant, antimicrobial and cytotoxic activities were evaluated. For chemical characterisation, phenolic compounds and essential elements were analysed as well as total phenolic contents. Subcritical water extracts exhibited the strongest antioxidant activity with the highest content of phenolics. Minimum inhibitory concentrations for analysed extracts were in the range from 9.76 to 156.25 mu g/mL in antimicrobial assays. The extracts exerted prominent cytotoxicity against different cell lines. Rutin was detected as the major compound in the studied extracts and these extracts were also rich in essential elements. Our study suggested that subcritical water extract of aronia stem could be considered as a new raw material in developing novel functional/industrial products.

AB  - Apigenin is a phytochemical which has been associated with numerous beneficial health effects. However, due to its low concentration and poor bioavailability, isolation from natural sources is very difficult. Subcritical water (SCW) is an excellent solvent for the extraction of moderately polar and non-polar flavonoids. Carefully balanced moderate hydrolytical potential of SCW was used in this work to liberate apigenin from its bound forms. In this research simultaneous extraction and hydrolysis of apigenin bound forms from chamomile have been performed. Optimal operation parameters for maximum yields of apigenin have been investigated and defined (solvent-to-sample ratio 1:30; agitation rate 3 Hz; pressure 45 bar; temperature 115 degrees C; time 30 min). Apigenin was further isolated in its pure form from water extracts obtained under optimal conditions using column chromatography. The purity of isolated compound was confirmed by spectroscopic analysis. Biological activity of extracts obtained under optimal conditions were determined as well. In order to identify polyphenolic compounds UHPLC-HESI-MS/MS analysis was performed.

Despite the numerous studies concerning the biological activities of this plant, there are only several studies regarding the chemical composition of stinging nettle (SN) leaves. Deeper chemical investigation revealed the presence of different class of compounds (polyphenols, phenolic acids, fatty acids, carotenoids, elements and minerals) in SN leaves. Results showed the chlorophylls and carotenoids contents of 304.63 mg 100 g(-1) and 69.07 mg 100 g(-1), respectively. The most abundant fatty acids were C18:3 (67.98 mu g g(-1)), C16:0 (60.97 mu g g(-1)) and C18:2 (55.99 mu g g(-1)), among terpenes linalool was dominant compound (5.1 mg g(-1)), while dominant trace element was iron with the content of 150.97 mu g g(-1). Such chemical profile is significant and indicate the wide range of possible further usage of this plant.

AB  - The main goal of this research was mathematical modelling and numerical simulation of the supercritical fluid extraction (SFE) process of coriander (Coriandrum sativum L.) seeds. SFE was performed at different set of process parameters: pressure (100, 150 and 200 bar), temperature (40, 55 and 70 degrees C) and CO2 flow rate (0.2, 0.3 and 0.4kg/h). Both applied empirical models, derived from models developed by Brunner and Esquivel et al., adequately described SFE process. Second objective was to determine effects of investigated SFE parameters on total extraction yield. Furthermore, calculated parameters from the empirical models were used for the calculation of initial slope, which was successfully used for optimization using artificial neural network (ANN). Optimized SFE conditions for maximized initial slope, i.e. initial rate of the solubility-controlled extraction phase, were pressure of 200 bar, temperature of 40 degrees C and CO2 flow rate of 0.4 kg/h.

SFE was performed at different set of process parameters: pressure (100, 150 and 200 bar), temperature (40, 55 and 70 degrees C) and CO2 flow rate (0.2, 0.3 and 0.4kg/h). Both applied empirical models, derived from models developed by Brunner and Esquivel et al., adequately described SFE process. Second objective was to determine effects of investigated SFE parameters on total extraction yield. Furthermore, calculated parameters from the empirical models were used for the calculation of initial slope, which was successfully used for optimization using artificial neural network (ANN). Optimized SFE conditions for maximized initial slope, i.e. initial rate of the solubility-controlled extraction phase, were pressure of 200 bar, temperature of 40 degrees C and CO2 flow rate of 0.4 kg/h.",

AB  - Biologically active compounds were isolated from stinging nettle (Urtica dioica L.) leaves using non-conventional extraction techniques such as ultrasound-assisted (UAE), microwave-assisted (MAE) and subcritical water extraction (SCW). Based on the extraction efficiency of six various solvents determined preliminary, water was selected as appropriate solvent for further extraction. The highest total phenolics (463.59 mg CAE/g SN) and flavonoids (11.00 mg CE/g SN) contents, and antioxidant activity (DPPH radical scavenging (IC50 = 16.93 mu g/mL), reducing power (EC50 = 30.07 mu g/mL) and polarographic assays (HPMC = 243.2%/mL) were ascribed to SCW extract. Cytotoxic and antimicrobial assays also confirmed domination of SCW technique. Superior cytotoxic activity against Hep2c, RD and L2OB cell lines (13.42 mu g/mL, 9.69 mu g/mL and 7.52 mu g/mL, respectively) and potent antimicrobial activity extract against Staphylococcus aureus (MIC = 9.76 mu g/mL) were also observed. The highest number of individual phenolic compounds were found in MAE extract. Rutin was identified as the most dominant compound in UAE, MAE and SCW extracts (578.36 mu g/g, 722.83 mu g/g and 215.49 mu g/g, respectively), while sinapic acid as the most dominant phenolic acid (50.49 mu g/g, 63.12 mu g/g and 18.08 mu g/g, respectively).

AB  - Satureja hortensis L. (summer savory) is herb from Lamiaceae plant family known by its usage in folk medicine and cooking. Despite these facts, this plant was not well studied regarding the application of nonconventional extraction techniques and utilization of prepared extracts. Thus, aim of this study was to prepare extract using conventional (maceration and Soxhlet) and non-conventional (ultrasound-assisted, microwave-assisted and subcritical water) approaches, to establish their chemical profile and biological activity using different assays and methods. Results confirmed the domination of subcritical water approach for isolation of natural compounds, following by microwave-assisted extraction. High performance liquid chromatography with photodiode array detection (HPLC-PDA) analysis confirmed the presence and domination of rosmarinic acid in conventionally prepared extracts, while rutin and quercetin dominated in non-conventionally prepared ones. Antioxidant and cytotoxic assays followed the trends of previous analysis, where the highest activity was exhibited by subcritical extract. Thus, results showed that extracts may be applied in food and pharmaceutical industries for utilization.
