AIM: To establish the quality standard for Fenghan Ganmao Granules. METHODS: TLC was used to identify Radix Puerariae, Pericarpium Citri Reticulatae and Radix Glycyrrhizae. The contents of ephedrine hydrochloride and pesudoephedrine hdrochloride were determined by HPLC. RESULTS: The linear range of ephedrine hydrochloride was 0.16 - 8.07 ?g, r= 0.999 9 . The average recovery was 97.00% . The linear range of pesudoephedrine hydrochloride was 0.06 - 2.86 ?g, r= 0.999 9 . The average recovery was 98.32% . CONCLUSION: The methods are simple. The result is accurate and the reproducibility is good. There mothods can be used as the quality control of Fenghanganmao Granules.
