Abstract:
Objective To establish the quality control method for Youqing Granules. Methods Qualitation discrimination of Rhizoma Cyperi and Raidix Paeoniae in this formula was identified by TLC. Quantitive analysis of Astragaloside A which is the effective element of the formula was adopted by RP-HPLC-ELSD. Result The specks in TLC were clear and easy to discriminate. The precision and reproducibility of the RP-HPLC-ELSD method were fine. In 1.032～5.16 ?g, the content of Astragaloside A had good linear relationship. The average recovery rate of sample was 99.0516 %, and RSD=1.05%. Conclusion The quality standard established on this study can control the quality of the products, the method is viable.
