Application of natural deep eutectic solvent (NADES) citric acid-glucose-based microwave-assisted extraction (MAE) method for total polyphenol content (TPC) enriches the use of Eleutherine bulbosa (Mill.) bulb more widely and commercially. Therefore, this study aims to optimize NADES citric acid-glucose-based MAE on the TPC from E. bulbosa bulbs using response surface methodology (RSM). In the present study, the dried sample of E. bulbosa bulb was extracted using the NADES based MAE. Determination of TPC was conducted using Folin-Ciocalteau reagent and standard gallic acid, then measured using a UV-Vis spectrophotometer at 761 nm. Extraction condition optimization of the NADES based MAE method was performed using RSM with Box Behnken Design (four-factors-three-levels and 29 runs) on Design Expert v12. Based on the results study, the optimum condition extraction on the TPC enrichment was obtained at the NADES ratio (citric acid: glucose) 1:1 g/g; solid-liquid ratio 1:8 g/mL; extraction time of 15 min; and 270 Watt microwave power. The confirmation test and scale-up (50 g samples) were obtained with a 61.63 ± 2.23 mg GA/g sample.

This study aims to determine the effect of citric acid-glucose based microwave assited extraction (MAE) method on total polyphenols content from (Peperomia pellucida [L.] Kunth) herbs. Dried samples were extracted using green solvent glucose citric acid with a ratio of 1: 1 g/g, 3: 1 g/g, and 5: 1 g/g, respectively, 30% microwave power for 5 minutes, and 1:5 g /mL solid-liquid ratio. Then the obtained extract solution was performed determination total polyphenols content using Folin-Ciocalteu reagent, and the absorbance was measured using a UV-Vis spectrophotometer at 791 nm. Based on the results, obtained total polyphenols content according to the extraction condition namely 214.405 mg GAE/g sample (3: 1 g /g solvent), 84.833 mg GAE /g sample (1: 1 g /g solvent) and 53,9451 mg GAE/g sample (5: 1 g /g solvent), respectively. This study is a preliminary data about the use of citric acid-glucose based microwave assisted extraction method on total polyphenols content from this plant quickly, easily and efficiently.

Deep eutectic solvents (DESs) have attracted significant attention as green media for the extraction and separation of natural compounds from Chinese medicine. In this study, a hydrophobic DESs-based microwave-assisted extraction (MAE) was successfully used to efficiently extract baicalin from Scutellaria baicalensis Georgi. Firstly, DecA: N4444-Cl (DES-1 , molar ratio 1 : 2) was screened and selected as the most appropriate DES by comparing the extraction yield in different hydrophobic DESs. Based on the extraction yield of baicalin, response surface methodology (RSM) was employed to model and optimize the parameters (extraction temperature, liquid-solid ratio, and extraction time). Furthermore, the maximum yield of 106.96 mg·g−1 was achieved under optimum conditions in DES-containing aqueous solutions (33 vol% water content), which reached a similar level that was conducted using the pharmacopoeia procedure (104.94 mg·g−1). These results indicated that the proposed method is an excellent alternative for the extraction of baicalin.

The present study investigates recovery of polyphenolic compounds from ripe mango ( Mangifera indica L.) peel using deep eutectic solvents based on microwave-assisted extraction method. Lactic acid/sodium acetate/water (3:1:4) screened out from eight different types of deep eutectic solvent systems was used as extractant. A Box–Behnken design along with response surface methodology was applied to optimize the effect of microwave power (W), time (min), and liquid-to-solid ratio (mL g−1) on polyphenol extraction. The optimized conditions determined were power of 436.45 W, time of 19.66 min, and liquid-to-solid ratio of 59.82 mL g−1. Under the optimal conditions, the recovery of total phenolic content, ferric reducing antioxidant power, and 2,2-diphenyl-1-picrylhydrazyl scavenging activity was 56.17 mg gallic acid equivalent g−1 dw, 683.27 µmol ascorbic acid equivalent g−1 dw, and 82.64 DPPHsc%, respectively. High Performance Liquid Chromatography (HPLC) analysis revealed mangiferin as the prominent phenolic compound in the mango peel extracts. Microwave-assisted deep eutectic solvent extraction showed remarkable effects on the extraction efficiency of phenolic compounds as revealed from scanning electron microscopy analysis. Rancimat test results revealed that the oxidative stability almost doubled upon addition of purified mango peel extracts to the sunflower oil and thus paving way for the use of mango peel waste as a potential source of antioxidants.
