微波辅助萃取葛根中有效成份的研究

Study on Microwave-assisted Extraction of Active Constituents in Radix Puerariae

摘要: 目的以总黄酮和葛根素的含量为指标，研究微波辅助萃取葛根的提取工艺。方法采用连续微波辐射方式进行微波萃取参数的单一因素考察。结果微波功率、辐射时间、溶剂用量、原料粉碎度、原料含水量等工艺参数的选择对葛根中有效成分的提取均有影响。结论微波辅助萃取比传统加热回流提取葛根的效果好，从单一因素观察，优化工艺条件为：微波功率510W、辐射时间10min，同时增加溶剂用量、提高原料粉碎度、延长原料浸泡时间将有利于葛根中有效成分的提取。
