摘要
目的优选人参首乌胶囊回流制备工艺。比较回流提取、渗漉提取对人参首乌胶囊有效成分的影响。方法按正交实验设计,高效液相色谱法(high performance liquid chromatography,HPLC)测定人参皂苷Rg1、二苯乙烯苷含量,以人参皂苷Rg1和二苯乙烯苷综合转移率(1:1)为指标,分别考察了乙醇浓度(%)、乙醇用量(倍)、提取时间、提取次数(次)对回流提取的影响;比较了回流提取与渗漉提取的优劣。结果最优提取方法为8倍50%乙醇加热回流提取1次,每次1.5 h。结论该制备方法简便、可行、稳定性高,为工业生产提供依据。
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 (1:1 )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 are:with 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.
