摘 要 ：黄芩甙在配制时定量加入含量稳定;用乙醇提取双黄连有效成分,提取次数及乙醇浓度对黄芩甙含量影响不大,可一次醇提。含醇量以85%为好;pH值影响较大,应控制在7.0～8.0之间;配制时,活性炭用量以0.2%为宜。

Abstract:The content of haicalin is stable when baicalin is added quantitatively in preparation. The time of extraction of the effective components of SHL with alcohol and the concentration of alcohol have little effect on the content of baicalin. The components can be extracted once, and the content of alcohol is preferably 85%. The pH level has greater influence on the content of baicalin, and should be controlled between 7.0 to 8.0. 0.2% activated carbon is suitable in preparation.
