Study on the preparation process of Radix Ginseng Capsules / 中国生化药物杂志

ABSTRACT

Objective To screen and optimize the preparation process of Radix Ginseng Capsules.This paper compares the reflux extraction and effects of infiltration percolation extraction to the renshenshouwu capsules.Methods Based on the Orthogonal test,the content of ginsenosides Rg1 and Stilbene glycoside were measured by HPLC.The transferring rates of ginsenosides Rg1 and Stilbene glycoside (11 )were regarded as the index to evaluate extracting conditions ,such as the ethanol concentration (%),consumption of alcohol (times),extraction time and extraction times (times). Results The optimum extract conditions of ginsenosides Rg1 and Stilbene glycoside arewith 8 times volume of 50%concentration ethanol as the extract liquid,to refluxing extract 1 times,1.5 h every time.Conclusion The preparation method is simple,practical,high stability and provides the basis for industrial production.
