Extract Process Optimization of Peoniflorin and Glycyrrhizic Acid in Yinxieling Tablet by Orthogonal Design
Objective:Optimizing the extract process for Yinxieling tablet.Method:The content of peoniflorin and glycyrrhizic acid in the extract was used as the index
and the concentration was determined by HPLC.The concentration of alcohol
extract time and number of times were considered.The orthogonal test was used for optimization.Result:The optimum extract process was as follows:70% alcohol extracted for 0.5 h
the extract number of times was twice.Conclusion:The optimum process provided a high yield for both three components
