Optimization of Water Extraction Technology for Qiju Granule by Orthogonal Test

Men Jiu-zhang

Abstract

Objective:To optimize extraction process of Qiju granule.Method:With the content of astragaloside IV and extract rate as indexes,extraction process was optimized by L9(34) orthogonal method.Result:Optimum extraction technology of Qiju granule was as follows:extracted 2 times with 18 times the amount of water,1 h each time.Conclusion: This optimized extraction process was reasonable and feasible.
