Abstract:
Objective To establish a method of HPLC assay for determining stilbene glucoside in Zishen Ningshen Pills(ZNP),and to study the influence factors on the content of stilbene glucoside in the process of preparation.Methods HPLC was used for the determination of stilbene glucoside in ZNP.Through simulation the process of preparation,the stilbene glucoside content in the intermediate products was determined by HPLC,and its retention rate and metastasis rate were also investigated.Results The resolution and the linearity of stilbene glucoside were fine,the average recoveries being 98 % ～ 102 %.The retention rate of stilbene glucoside in the drying powder was 60.3 %,lower than that in the original medicinal powder.Conclusion The quantitative method for determining the ingredients in ZNP is simple,feasible and reproducible,and is beneficial for quality control of ZNP.The drying process under normal pressure is the main influence factors of the decrease of stilbene glucoside content,and the decompression drying can be taken into account to take the place of the atmospheric drying.
