白花蛇舌草中总黄酮微波辅助提取工艺研究

摘要

研究了白花蛇舌草中总黄酮的微波辅助提取工艺,在单因素实验基础上,采用正交实验对提取工艺进行了优化.确定出最佳提取条件为:液料比20∶1 mL/g、φ(乙醇)=80％、微波时间120s、微波功率400W、微波温度70℃,在此条件下,总黄酮的提取率达3.46％.%Microwave-assisted extraction process of total flavonoids in hedyotis diffusa was studied.The extraction process was optimized by orthogonal experiment based on the single factor experiment.The optimum extraction conditions were determined as follows:liquid to solid ratio of 20 ∶ 1 mL/g,ethanol concentration of 80 ％,microwave time of 120s,microwave power of 400W,microwave temperature of 70 ℃.The extraction ratio was up to 3.46％ on the optimum conditions.
