[Objective] The research aimed to optimize the water extraction process of Shiqing granules. [Method]With dry paste rate and the content of baicalin as examining index,the add water,extracting times and extracting time as factors,the best water extraction process was optimized by L9( 34) orthogonal experimental method. [Result]The best extraction process was 10 times the amount of water,decoction extract 2times,each time 1 h.[Conclusion]Baicalin water extraction processing conditions were stable,the method ...
