Title: Study on Optimum Extraction Process for Fuyanling Capusules by Orthogonal Design
Abstract: Objective To optimize the extraction technology for medicimal materials in Fuyanling capsules.Methods The extraction method of Fructus Cndii and Radix Sophorae Flavescentis was determined by orthogonal design with the content of osthole taken as marker , The extraction method of Folium Callicarpae,Herba Agrimoniae and Radix Stemoniae was determined by orthogonal design with the weights of water and n butanol extraction taken as markers.Results The optimal conditions are as follow: Fructus Cndii and Radix Sophorae Flavescent were extracted with 85% alcohol,adding 14 folds alcohol as much as medicianl material,extracting two times(1 h per time);Folium Callicarpae,Herba Agrimoniae and Radix Stemoniae were extracted with water,adding 12 folds water as much as medicinal material,Decocting two times(1 h per time).Conclusion The extraction conditions above are the best.
