微波辅助低共熔溶剂提取薏苡叶总黄酮的工艺研究OACSTPCD
Microwave-assisted deep eutectic solvents extraction of total flavonoids from Coix leaves
采用低共熔溶剂作为提取溶剂,对薏苡叶总黄酮进行微波辅助提取.通过单因素试验研究了低共熔溶剂的体系、组成比例、含水量、料液比对提取效率的影响.在此基础上,选择微波提取工艺参数温度、时间和功率进行L9(33)正交试验,得出了总黄酮的最佳提取工艺参数.微波辅助低共熔溶剂提取总黄酮的最优工艺:20倍药材量的30％含水量的氯化胆碱/乙二醇,摩尔比为1∶3,微波提取温度55℃,功率500W,时间15 min.
Use deep eutectic solvents (DESs) as extractive solvents and microwave-assisted extraction of total flavonoids from leaves of Coix.The effects of different deep eutectic solvents,Choline chloride (ChCl) /Glycol ratio,DESs/water ratio and solid-liquid ratio on the extraction yield of total flavonoids from leaves of Coix were investigated by single factor test.Based on the results from single factor test,the extraction technology (temperature,extraction time a…查看全部>>
