Abstract:
AIM: To establish the quality standard for Compound Songluo Granule (Rhizoma Corydalis, Radix Angelicae Sinensis, Lichen Usneae). METHODS:Rhizoma Corydalis, Radix Angelicae Sinensis were identified by TLC. Usnic acid in Lichen Usneae was determined by TLCS. RESULTS: Rhizoma Corydalis, Radix Angelicae Sinensis could be detected by TLC. Usnic acid showed a good linear relationship at the range of 0. 50～2.50 ?g, r=~0.999 9. The average recovery was 97.5% and RSD was 2.61%, respectively. CONCLUSION:The method is available with a good reproducibility and can be used for the quality control of Compound Songluo Granule.
