Study on Quality Standard for Huashengping Capsules / 中国药师

ABSTRACT

Objective:To establish the quality standard for Huashengping capsules. Methods: Milkvetch Root, Hedyotis diffusa Willd and Salvia miltiorrhiza were identified by TLC. The content of astragaloside A was detected by HPLC. The column was Kormasil C18(250 mm ×4.6 mm, 5 μm) and the flow rate was 1.0 ml·min-1. The mobile phases was a mixture of acetonitrile-water (32∶68 ) . The detection wavelength was 203 nm. The column temperature was 25℃ and the sample size was 20μl. Results:The TLC chro-matography spots were clear. Astragaloside A was linear within the range of 2. 000-10. 000 μg(r=0. 999 6) and the average recovery was 100. 8%(RSD=1. 9%,n=6). Conclusion:The method is simple, accurate and reliable, which can be used in the quality con-trol of Huashengping capsules.
