“…A central composite design was utilized to determine the optimized condition in MAE extraction of total phenolic content (TPC), total flavonoids content (TFC), total monomeric anthocyanin content (TAC), total tannins content (TTC) and antioxidant activity from the juçara waste; non-coded and coded factors (microwave power, exposition time, and solvent concentration) are exhibited in Table 1. Although several factors such as microwave power, microwave temperature, exposure time, composition of solvent, solids to solid ratio and extraction cycles, can affect the extraction efficiency in MAE, studies show as the main independent variables microwave power, exposure time and solvent concentration (Li et al, 2012(Li et al, , 2013Zeković et al, 2016). To predict the optimal conditions of the extraction process experimental design software (Minitab ® 17.1.0, USA) package was used for the regression analysis of the data to fit a second-order polynomial equation (Equation 1) for the regression analysis of the data.…”

“…MAE present advantages compared with conventional extraction, which is considered a green technology (Zeković et al, 2016). Powder of Juçara waste was subjected to MAE utilizing a DGT 100 Plus system (Provecto Analytics Ltd., Jundiaí, SP, Brazil) for antioxidant extraction.…”

“…Ethanol, a green safe solvent, (Kukula-Koch et al, 2013;Li et al, 2012) was utilized due to efficiency on solubilizing bioactive molecules from vegetable matrixes (Espinosa-Pardo et al, 2014;Fang, Wang, Hao, Li, & Guo, 2015;Sharma et al, 2014). In addition, previous studies using MAE to the extraction of antioxidant compounds from fruits determined that the concentration of the solvent, microwave power and exposition time were independents variables (Dahmoune et al, 2014Fang et al, 2015;Kim et al, 2012;Li et al, 2012Li et al, , 2014Zeković et al, 2016).…”

“…First, the extraction combination decreased efficiency by raise power but after 550 W increased. Probably because increased diffusion rate and solubility of the target compounds in the solvent were affected by temperature (Fernández-Ponce, Casas, Mantell, & Martínez de la Ossa, 2015) and higher power must be excited phenolic molecules (Zeković et al, 2016). Also, an increase of ethanol concentration increase TPC yield, probably for the fact of solvent polarity declined and solubility of molecules increased.…”

“…In this way, microwave-assisted extraction (MAE), an emerging green technology, have demonstrated to be a promising method for the recovery of bioactive compounds such as total phenolics, flavonoids, anthocyanins, and tannins from plants. (Dahmoune et al, 2014;Dahmoune, Nayak, Moussi, Remini, & Madani, 2015;Dairi et al, 2015;Kim et al, 2012;Li et al, 2012Li et al, , 2014Zeković, Vladić, Vidović, Adamović, & Pavlić, 2016). Although, to the best of our knowledge the MAE has not been used for extraction of natural antioxidant compounds from E. edulis.…”

The Euterpe edulis (Juçara) is native to Brazil, which berries and wastes present high antioxidant content. Therefore, in this study, microwave-assisted extraction (MAE) was investigated for antioxidant compounds extraction from E. edulis waste and maximized antioxidant activities using response surface methodology coupled with a central composite design. Three factors were observed: microwave power (400/500/600 W), exposition time (30/60/90 sec) and ethanol concentration solvent (40/60/80%). The extracts were characterized by determination of total phenolic (TPC), flavonoids (TFC), monomeric anthocyanins (TAC), tannins content (TTC), and in vitro antioxidant assay (AA%). The yield of TPC, TFC, TAC, and TTC varied at 595.43-2171.34 mg GAE·100 g DM , respectively. The optimal MAE parameters for TPC was microwave power 668.18 W, exposition time 110.45 s and aqueous ethanol concentration 93.64%, for TFC same parameters observed; though for TAC the different parameters were 532.28 W, and for TTC 9.55 s. However, for antioxidant activity, the parameters were 668.18 W, 110.45 s time and 64.41% of aqueous ethanol solvent. Therefore, this methodology was successfully applied for optimal extraction of total phenolics, flavonoids, monomeric anthocyanins and tannins from juçara waste and obtain optimal antioxidant activity.

This research work was carried out to explore the influence of extraction methods on the extraction of antioxidant from Asparagus racemosus roots. The microwave-assisted extraction (MAE) method was more efficient as compared with continuous shaking extraction (CSE) method in terms of total phenolic content (TPC), total flavonoids content (TFC), 2,2-diphenyl-1picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), and total antioxidant capacity (TAC) content in the ethanolic extract of A. racemosus roots. Box-Behnken experimental design of response surface methodology (RSM) was used to optimize MAE method for three process parameters viz. solvent concentration (SC: 40%-90% v/v), extraction time (ET: 10-30 min), and microwave power (MP: 360-720 W). Model fitness of the experimental data was determined by multiple regression analysis and analysis of variance. The optimum targeted parameters were obtained as 65% v/v SC, 23 min ET, and 560 W MP, and the corresponding responses TPC, TFC, DPPH, FRAP, and TAC were found to be 9.377 mg GAE/g, 177.03 mg QE/g, 65.70%, 193.35 mM Fe +2 /g, and 496.97 mg AAE/g with a desirability of 0.95. Fuzzy modeling with Mamdani-type fuzzy inference was also utilized to obtain the most optimal conditions for specified process parameters and responses under the set of rules for process parameters and responses. The estimated results of responses by both RSM and fuzzy model showed good agreement with the experimental values.

BACKGROUND Sweet cherries (Prunus avium L.) and sour cherries (Prunus cerasus L.) contain substantial amounts of anthocyanins and polyphenolics, and their stems have been used in traditional medicine for centuries. However, comparative data on the composition of sweet and sour cherry stems using the same analytical methodologies are limited. Moreover, there is no data in terms of biological activity of subcritical water extracts of cherry stems. RESULTS AND DISSCUSION Results obtained by using several assays that focused on different mechanisms showed that subcritical water extracts of sour and sweet cherry stems were powerful antiradicals and antioxidants. Anti‐proliferative properties measured by MTT (3‐[4,5‐ dimethylthiazol‐2‐yl]‐2,5 diphenyl tetrazolium bromide) test showed prominent cytotoxicity against different tumor cell lines. Inhibitory concentrations obtained were in the range 8.38–11.40 µg mL‐1. GC–MS (gas chromatography mass spectrometry) analysis showed the presence of alcohols, fatty acids, organic acids and other organic compounds. However, the chemical compositions of the two samples observed were similar, indicating similar chemical composition of sour and sweet cherry stems. CONCLUSION Subcritical water extracts of cherry stem demonstrated excellent biological activity and the potential to be used for pharmaceuticals or supplements due to confirmed high antioxidant, antiradical and antitumor activity. © 2017 Society of Chemical Industry
