| 摘 要： | 本研究运用新型分离方法微波辅助提取法(MAE)来提取黄芩中的黄芩苷.分别选用水、乙醇、氯仿、正己烷、石油醚作为萃取介质,在间歇微波辅助提取装置中,对10 g黄芩原料进行微波辅助提取实验,得出微波辅助提取的最佳工艺为:黄芩原材料粉碎粒度200目,溶剂为60%乙醇溶液,微波辐射8 min.同时还对微波辐射时间、溶剂、物料粒度等条件对黄芩苷得率的影响进行了探讨.结果表明微波辅助提取黄芩中的黄芩苷,具有质量稳定、速度快、萃取效率高等特点.

| Abstract: | A new method,namely microwave-assisted extraction(MAE),is used to extract baicalin from S.baicalensis.Water,ethanol,chloroform,n-hexane,petroleum were used separately to extract baicalin in a MAE apparatus.The result showed the optimum condition as follows:60% alcohol as sovent,granularity of raw material 200 mesh,duration of microwave irradiation 8 min.Effects of different solvents,different grain sizes of S.baicalensis Georgi and duration of microwave irradiation on yield of baicalin were discussed.Results showed that microwave-assisted extraction is (efficient),simple and rapid for extraction of baicalin from S.baicalensis. |
