Objective: To improve the quality standard of Huanglian Shangqing Tablets. Methods: TLC was used to identify the rhubarb, wolfberry and jaundice. The content of baicalin was determined by high performance liquid chromatography. RESULTS: Rhubarb, Rhizoma jasminoides and Scutellaria baicalensis Georgi could be detected in thin-layer chromatography. Baicalin had good linearity in the range of 4.8 to 484.8 μg·ml -1. The average recovery was 100.8%, and the RSD was 1.6%. (n=9). Conclusion: The method is simple, accurate and specific. It can more effectively control the quality of Huanglian Shangqing Tablets.
