Analysis on Factors Affecting Production Process of Zhongsheng Pills
众生丸生产过程影响因素探讨（一）

This study was aimed to discuss possible existed problems in the production process of Zhongsheng pills and the solving methods. Factors which affect the extraction process of Zhongsheng pills were analyzed by HPLC. The retention rate of paeoniflorin, polydatin and baicalin were determined. The results showed that dynamic extraction is one of the important conditions to ensure that the production is consistent with the experimental study. It is concluded that by analyzing targeted research factors in the production process, the extraction rate of active ingredients are ensured. This study provides references for the production of Zhongsheng pills.
