Abstract

OBJECTIVE Study on quality standards for Herba Lysimachiae granules. METHODS Chinese thorowax root, corydalis and Rhubarb of Herba Lysimachine granules prescription were identified by TLC. The content of quercetin in Herba Lysimachine granules was determined by HPLC. RESULTS The chromatogram for identification by TLC was distinct and hightly specific. A good linear relationship was obtained in a range of quercetin concentrations from 1.896 0 μg·mL-1 to 30.336 0 μg·mL-1(r=0.999 8). The average recovery was 97.73%, RSD was 1.34%. CONCLUSION The method is simple, rapid and specific, and can be used for the quality control of the mixture.
