丹参的微波提取研究

目的]研究用微波提取丹参优化工艺。方法]以丹参的脂溶性成分丹参酮ⅡA和水溶性成分丹参素、原儿茶醛为指标，用均匀试验设计法对丹参的微波提取工艺进行优化。并与传统工艺比较。结果]丹参以6倍量95％乙醇、微波功率320W提取30min，药渣再以12倍量水，320W微波提取两次对丹参酮ⅡA，丹参素和原儿茶醛三种指标成分的提取量，相当于或优于现行法的提取量。结论]用微波提取丹参酮ⅡA较易，而对水溶性成分丹参素和原儿茶醛相对所需时间较长。

Microwave Extraction of Radix Salviae Miltiorrhizae

Objective] To study the optimizing technics of the extraction of Rad ix Salviae Miltiorrhizae with microwave. Methods] Taking Tanshinone IIA(lipo soluble component),Radix Salviae Miltiorrhizae elements(water-soluble componen t) and catechu aldehyde as the indexes,a method of uniform experimental design was applied to optimize the technics of microwave extraction and compared with the traditional technics. Radix Salviae Miltiorrhizae was extracted for 30 minut es with of 95% alcohol of 6-fod amount and microwave power of 320 w first , tha n the drug residue was extracted twice with water of 12-fold volume and 320 w mi crowave. Results] The extracted amount of three components is equal or superi or to that extracted by the method being used now. Conclusion] The extract of Radix Salviae Miltiorrhizae ketone IIA with microwave is easy, but a relative l onger time is needed for xtracting Radix Salviae Miltiorrhizae elements and cate chu aldehyde.
