摘要:

白藜芦醇因其具有多种保健作用而受到人们广泛关注,经研究测定在桑叶中有一定的含量。本文采用有机溶剂回流法提取桑叶中的白藜芦醇,确立了提取的最佳条件: 提取溶剂为乙醇;回流时间为105 min;乙醇浓度为80%;物料比为1:13;回流温度为60 ℃。原料经回流提取、过滤除渣后旋蒸得到白藜芦醇浓缩液,再用高效液相色谱法测定白藜芦醇的含量。

Abstract:

The mulberry leafs contain amount of resveratrol which has various health effects. In this experiment, the optimum conditions of extracting resveratrol from the mulberry leaf with the reflux was established as follows: the solvent was alcohol, the temperature was 60 ℃, the time was 105 minutes, the concentration of alcohol was 80%, and the material rate was 1:13. And the content of resveratrol was determined by HPLC.

Key words: resveratrol, mulberry leaf, extraction technology, HPLC
