丹参多酚酸提取工艺的研究

Study on the Extraction Procedure for the Salvianolic Acids of Salvia miltiorrhiza

目的优选丹参多酚酸最佳提取工艺。方法以丹参多酚酸B和总丹参多酚酸含量为指标成分,对丹参多酚酸提取工艺进行优选。结果优化工艺为:12倍量30%乙醇回流提取3次,1 h/次。丹参多酚酸B和总丹参多酚酸含量分别为57.7%,66.9%。结论该工艺合理,丹参多酚酸成分提取完全,具有较好的经济效益。

Objective To optimize the extraction procedure for the salvianolic acids of Salvia miltiorrhiza.Methods The optimum conditions of extraction process for salvianolic acids of Salvia miltiorrhiza was selected with the contents salvianolic acid B and salvianolic acid as indexes by experimental design.Results The optimal extraction procedure was refluxing extraction of salvianolic acids,and the Salvia miltiorrhiza was extracted with 30% ethanol times,1 hours per time.The contents of salvianolic acid B and salvianolic t were 57.7%,66.9%.Conclusion The optimum preparative procedure is reliable.Salvianolic acids were extracted completely,and it has the high economic benefit.
