复方丹参提取工艺的研究

目的：筛选最佳的以丹参为君药的复方中药的水提取工艺。方法：以水溶性酚酸为工艺筛选指标性成分，采用正交设计方法筛选最佳提取工艺及其条件。结果：最佳提取工艺为将药材粉碎过20目筛，加8倍量水浸泡1．5h，煎煮2次，第1次1．5h，第2次加6倍量水，煎1．0h。结论：该提取工艺酚酸转移率高（88．3％），并经中试验证，合理可行。

INVESTIGATION ON EXTRACTION PROCESS OF COMPOUND SALIVA MILTIORRHIZA

Objective:To screen the best extraction process of compound Chinese medicine of miltirone used as a main medicine with water. Method: By using soluble salvianolic acid as screening index component,the best extraction process and condition were screened with orthogonal test method. Result: The best extraction process was as follow: The herbal medicines were crushed to 20 Mu sieve, added 8 times water, soaked for 1.5 h, decocted 2 times ,1.5 h and 1.0 h respectively. Conclusion: The extractive rate of salvianolic acid was higher (88.3%) by the process. The process was proved to be reasonable and feasible through production on a mode-rate scale.
