摘要：

In this study, an efficient extraction technique using a combination of ultrasound and natural deep eutectic solvents (NADESs) was developed. Some basic physical properties, including viscosity, polarity, and solubility, of thirteen NADESs prepared from natural components were investigated systematically. Results show that the solubility of rutin increased in choline chloride-and glycerol-based NADESs by 660-1577 times compared to water. NADESs with high rutin extractability can be designed by combining NADESs components. A maximum of 9.5 mg/g rutin was extracted from tartary buckwheat hull with extraction efficiencies of 95%. NADESs can be recovered and recycled. In addition, the biocompatibility and biodegradability of the tested NADESs were also evaluated. The results demonstrated that these NADESs were excellent solvents with extremely low toxicities and favorable biodegradabilities. Our findings suggest that NADESs can be used as green solvents for the extraction of bioactive ingredients. (C) 2016 Elsevier Ltd. All rights reserved.
