Study on Extraction of Compound Luronggubao Capsule

[Objective] The aim was to screen the best extraction technology of compound Luronggubao capsule.[Method] Applying orthogonal experiment design and taking icariin as observation indicators,added water amount,extraction times and extraction time as factors,extraction craft of fine luronggubao capsule was selected.[Result] The optimum condition of compound Luronggubao capsule was adding the volume of 10 times water,extracting for three times and extracting for 1.5 hours every time.[Conclusion] In accordance with the optimum extraction conditions,the rate of icariin extraction was the highest.This extraction process was feasible.
