“…k 2 (extraction rate constant) values were 2.07 × 10 −4 , 1.89 × 10 −4, and 3.01 × 10 −5 , where it decreased by temperature. Similar extraction rate constants change was also observed by other studies, where phenolic contents were extracted from different plant materials (Abishli et al, 2021; Albarri et al, 2021).…”

“…Singh et al (2011) observed the same microwave power effect when extracting phenolic antioxidants from potato skins with MAE. Similarly, Alberri et al observed a similar power effect on the MAE of polyphenols from Moringa oleifera leaves, where 17.30, 19.16, 19.35, and 19.94 mg‐GAE/g dried M. oleifera leaf were achieved by changing the power as 200, 300, 400, and 500 W (Albarri et al, 2021).…”

In this study, deep eutectic solvent has been used in order to propose an environmentally and green method for conversion of biowaste into high added-value products. A deep eutectic solvent system consisting of citric acid/ethylene glycol mixture (1/4, molar ratio) has been prepared to extract total polyphenols from sour cherry (Prunus cerasus L.) peels. Deep eutectic solvent-based microwave-assisted extraction has been used in order to evaluate mass transfer, kinetic, and thermodynamic parameters. According to the high Biot number values (1,487.23, 2,970.83, 3,974.28), an efficient contact between the total polyphenols and the deep eutectic solvent system has been confirmed. It is observed that the total amount of phenolic substances varies between 4.29 and 33.61 mg-GAE/g of fresh material. In this study, the pseudo-second-order kinetic model (R 2 > 0.90) has been successfully applied for the extraction of TPC during MAE. ∆H > 0, ∆S > 0, and ∆G < 0 denote an endothermic and spontaneous microwave-assisted extraction system for the solid-liquid extraction of TPC from sour cherry (Prunus cerasus L.) peels. Novelty impact statement: Polyphenolic compounds (anthocyanins and antioxidants)were extracted from sour cherry (Prunus cerasus L.) peels. Extraction kinetics of economical and environmental MAE method has been investigated for natural antioxidants. The structure of the DES-based MAE of bioactive substances from sour cherry peels will be able to understand comprehensively according to the thermodynamic parameters.

The biomass Solanum mauritianum (S. mauritianum) is an invasive weed specie; however, it is a source of medicinally important metabolites, as reported in literature, such as solasonine and solamargine. The study was directed at the optimization of microwave and aqueous two-phase-based extraction techniques which involved microwave-assisted extraction (MAE), aqueous two-phase extraction followed by microwave-assisted extraction (ATPE + MAE), and the “one-pot” microwave-assisted aqueous two-phase extraction (MA-ATPE) for extraction of solasonine and solamargine from leaves of S. mauritianum which was evaluated. The microwave-assisted extraction of solasonine and solamargine yielded optimums at 5.00 min, microwave power of 270 W, and solid/liquid of 0.1 g L−1 at an ethanol concentration of 60%. Application of a two-stage extraction (MAE + ATPE) in CaO-dried alcohol resulted in decreased amounts of solasonine and solamargine extracted. The best yields of solasonine and solamargine were achieved in the MA-ATPE method. Extraction of solamargine and solasonine using Na2CO3 in CaO-dried ethanol during MA-ATPE was approximately threefold and twofold greater than that of MAE + ATPE, respectively. Furthermore, extraction of solamargine and solasonine using NaCl in CaO-dried ethanol during MA-ATPE was approximately twofold greater than that of MAE + ATPE. The synergy of microwaves and salting-out in the “one-pot” MA-ATPE technique was shown to be a contributing factor for enhanced extraction of solamargine and solasonine from leaves of S. mauritianum. Application of this time- and energy-efficient extraction method could potentially be expanded for enrichment of medicinally important compounds from biomass of other medicinal plants.
