“…Also, an increase of ethanol concentration increase TPC yield, probably for the fact of solvent polarity declined and solubility of molecules increased. The same behavior has observed in Pistacia lentiscus and Vitis coignetiae (Dahmoune et al, 2014;Kim et al, 2012). This behavior was observed for phenolic compounds from Euterpe edulis peels and pulp near the seeds by Garcia-Mendonza et al (Garcia-Mendoza et al, 2017).…”

“…The effect between the exposition time (X 2 ) and ethanol concentration (X 3 ) are presented in Figure 1-A1, this can be observed the time and ethanol concentration is directly proportional to TPC yield, same behavior was observed in juçara pulp MAE (Cavalcanti et al, 2011), in coriander seed extracts (Zekovi et al, 2016), in Cammelia oleifera fruit (Zhang et al, 2011) and in Vitis coignetiae (Kim et al, 2012). Thus, the highest ethanol concentration increased extraction of compounds (Kim et al, 2012), this may be attributed the difference in dielectric properties of solvent towards microwave heating (Dahmoune et al, 2014).…”

“…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).…”

“…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.

Box-Behnken design (BBD), one of the most common response surface methodology (RSM) methods, was used to optimize the experimental conditions for ultrasound-assisted extraction of polysaccharides from Rhynchosia minima root (PRM). The antioxidant abilities and anticancer activity of purified polysaccharide fractions were also measured. The results showed that optimal extraction parameters were as follows: ultrasound exposure time, 21 min; ratio of water to material, 46 mL/g; ultrasound extraction temperature, 63˝C. Under these conditions, the maximum yield of PRM was 16.95%˘0.07%. Furthermore, the main monosaccharides of purified fractions were Ara and Gal. PRM3 and PRM5 exhibited remarkable DPPH radical scavenging activities and reducing power in vitro. PRM3 showed strong inhibitory activities on the growth of MCF-7 cells in vitro. The above results indicate that polysaccharides from R. minima root have the potential to be developed as natural antioxidants and anticancer ingredients for the food and pharmaceutical industries.

The phenolic compounds from alfalfa (Medicago sativa L.) are used as antioxidants and in native medicine. They play an indispensable role in defense and signal transduction of the plant under stress conditions. This exploration of the optimal extraction parameters of the total phenols from alfalfa by using ultrasonic‐assisted extraction (UAE) was aimed at providing a theoretical basis for better utilization of the total phenols in alfalfa. In this study, the effects of solvent volume fraction (A), extraction time (B), solid‐liquid ratio (C) and extraction temperature (D) on the total phenols content and the total antioxidant capacity of Medicago sativa L. WL363HQ after thrips infestation were determined through single‐factor experiments. Additionally, the extraction conditions of total phenols were optimized by using Box‐Behnken design (BBD) of response surface methodology (RSM). The results showed that the proposed model had a good fitting degree for total phenols extraction (R2=0.9564). The total phenols extraction from WL363HQ had significant relationship with solid‐liquid ratio (C) and extraction temperature (D) (P<0.05). The influence levels of the four factors on total phenols extraction were as follows: extraction temperature (D) > solid‐liquid ratio (C)>acetone volume fraction (A)>extraction time (B). The optimum extraction conditions of total phenols from WL363HQ were 50 % acetone, solid‐liquid ratio of 1 : 20 (g/mL), extraction time of 45 min and extraction temperature of 60 °C. The corresponding content and total antioxidant capacity under the optimized conditions were 15.76 mg g−1 and 28.79 μmol Trolox g−1. These results provided a new extraction method of total phenols from alfalfa.
