摘要
以柴胡中总皂苷和浸膏率为考察指标 ,应用正交设计优选柴胡的提取工艺 ,乙醇浓度、乙醇用量、回流提取次数、提取时间为影响因素 ,每个因素取三个水平。结果表明 ,最佳提取条件为 :80 %乙醇用量为药材量的 4倍 ,回流提取 4次 ,每次 6 0min ,优选得到的工艺稳定可行。
The orthogonal design was used to optimize extraction process of Radix Bupleuri with content of total saponin and yield of the extract as markers.Factors that have been chosen were ethanol concentration,ethanol consumption,extraction times and extraction time.Each factor had three levels.The result showed that the optimum extraction condition was 80% ethanol,4 times the amount of material,refluxing for 4 times,60 minutes each time.The optimized process was stable and workable.
