滁菊叶中黄酮类成分的提取工艺优化

摘要

By solvent- extraction process extraction folium of Dendranthema class ingredient, takesrate as the observation target, withdraws the flavanone morifolium ＇ Chuju＇ in flavanone class ingredient craft through or- thogonal test design research rope the optimized condition. The inspection on ethyl alcohol density, the material fluid compares, factors and extraction time to the folium of Dendranthema morifolium ＇ Chuju＇ in the flavanone class ingredient extraction effect has been done with, definite withdraws in the Dendranthema morifolium ＇ Chu- ju＇ the flavanone class ingredient technological conditions. The results show that Dendranthema morifolium ＇ Chuju＇ flavanone class ingredient optimum extraction technological conditions are A2B2C3, namely in the ethyl alcohol density 80%, material fluid 1： 25, extraction 2.5h rate is higher. Extraction in the Dendranthema morifolium rate than the traditional extraction flavanone method. Dendranthema morifolium ＇ Chuju＇ in the flavanone ＇ Chuju＇ the flavanone is easy to do and has higher%以溶剂提取法提取滁菊叶中黄酮类成分，以得率为观察指标，考察乙醇浓度、料液比、提取时间等因素对滁菊叶中黄酮类成分提取效果的影响，确定索氏提取滁菊叶中黄酮类成分的工艺优化。结果表明，滁菊叶黄酮类成分最佳提取工艺条件为A：B2C3，即在乙醇浓度80％、料液比1：25、提取时间2．5h滁菊叶中黄酮的得率较高。索氏提取滁菊叶中黄酮，方法简便，有较高的得率。
