摘要
目的 :优选茺蔚子的最佳提取工艺。方法 :采用正交试验法 ,以提取液中水苏碱含量为考察指标 ,对影响茺蔚子提取工艺的因素进行了研究。结果 :实验设计三因素中提取次数有显著影响。结论 :茺蔚子的最佳提取工艺为 :用 6倍量 5 0 %乙醇回流提取 3次 ;每次为 2h。
Objective To optimize the condions for the extraction of Fructus leonuri.Methods Conditions for the extraction were studied by orthogonal experimental design as guided by the content of stachydrine present in the extract.Results Significant effect was observed in times of extraction.Conclusion The optimum condion of Fructus leonuri was to be in a stata of hot reflux with six times of 50% ethanol for there times,the time was 2h each time.
