Abstract

Objective To optimize extraction technology of Gushuling,a compound preparation of Chinese medicine.Methods Orthogonal design was used to evaluate the icariin with astragaloside Ⅳ extraction rate as indexes.Data processing was carried out with comprehensive evaluation method for optimizing the extraction condition.Results Optimized extraction conditions were as follows:the drugs were decocted twice and 1h per time;at first water was added to 11 times and for the second time the amount of water was 8 times.Conclusion The optimized technology is stable and feasible.
