Artemisinin in Herba of Artemisia annuna from different places was determined by this new method. METHODS: The method utilized MeOH-H2O (75: 25) as mobile phase with flow rate of 1 ml/min, C18 (250 x 4.6 mm, 5 microm) column. The temperature of detector was 40 degrees C, the pressure of N2 was 3.5 bar, and gain value was 9. RESULTS: The calibration curves were linear within the range of 1 - 5 microg, and the average recovery was 99.33% (RSD = 1.97%). CONCLUSION: The method was rapid, convenient, and accurate. It can be used for the quality control of this herbal medicine.
