METHOD:The HPLC method was used to determine the content of swertiamarin in Swertia davidi Franch. The analysis was carried out on C 18 column. The mobile phase is MeOH-H2O(20∶80). Flow-rate: 0.8 ml/min.Wave-length:254 nm. RESULT: The method was simple and easy to hand. It had a good linear relationship.The liner range was 0.37~2.775 mg/ml and gave a correlation (r) of 0.9997. The recovery is 99.74% with RSD 1.58%. CONCLUSION:The method is easy to determine the content of swertiamarin in Swertia davidi Franch.展开更多
