Study on Preparation Technique and Quality Standard for New Shengfa Pills / 中国药师

ABSTRACT

Objective:To study the preparation technique and quality standard for new Shengfa pills. Methods: The best water extraction process of the medicinal herbs was optimized by orthogonal test using stilbene glucoside content and dry extract percent as the indices. The content of stilbene glucoside was determined by HPLC, and Hyssop and Chinese angelica in the preparation were identified by TLC. Results:The optimized preparation conditions were as follows12-fold water was used in the 3-time extraction with 1 h for each time. The spots in TLC were clear without interference from the negative control. Conclusion:The preparation process is reasona-ble and feasible in techniques with controllable quality.
