Ying Song

Abstract

Objective: To establish the quality control standard for Xiaozhi Solution(Radix et Rhizoma Rhei, Radix Scutellariae, Radix Paeoniae Rubra, Rhizoma Smilacis Glabrae, etc.) Methods: Radix et Rhizoma Rhei Radix Scutellariae、 and Radix Paeoniae Rubra in solution were identified by TLC. The contents of emodin chrysophanol were determined by HPLC. The average recovery of added sample were 99.10% ( RSD was 1.88% ) for emodin and 98.87% ( RSD was 1.21%) for chrysophanol. Results: The method was simple, accurate and specific. Conclusion: The method can be used for the quality control of Xiaozhi Solution.
