摘要

目的 :优选牛黄上清微丸提取方法。方法 :采用L9(34)正交实验

以大黄素、大黄酚及黄芩苷为指标评价大黄和黄芩的醇提取工艺;采用L9(34)正交实验

以栀子苷为指标评价栀子等其余药物水提取工艺。结果 :大黄、黄芩的醇提取部分最佳工艺为加5倍量70%乙醇回流提取3次

每次1.5 h;栀子等其余药物水提取最佳工艺为加10倍量水

提取2次

每次1 h。结论 :提取工艺设计合理

方法可行

对大生产有指导意义。

Abstract

Objective: To establish the best extraction method of Niuhuang Shangqing pellets. Method: L9 (34) orthogonal experiment was adopted to optimize the alcohol extraction process of rhubarb and baicalin with the yeild of emodin

chrysophanol and baicalin as evaluation target; L9 (34) orthogonal experiment was adopted to optimize the water extraction process of the rest herbs with the yeild of geniposide as evaluation target. Result :Optimum alcohol-extracting factors were 5 times of 70% alcohol

circum-fluence extracting for 1.5 h

for 3 times; Optimum water-extracting factors were 10 times of water

refluxing and extracting for 1h

for 2 times. Conclusion : The extraction method was designed reasonable and it was instructive to industrial production.
