ABSTRACT Objective: To establish an HPLC-ELSD method for determination the content of astragaloside in Tangshenkang granules. Method:The Phonomenex C18 column(150 mm×4.6 mm,5 μm)was used.Acetonitrilewater(32∶68) was used as the mobile phase. The flow rate of mobile phase was 0.8ml•min-1.The tube temperature of the detector was 105 ℃.The flow rate of pure air was 2.7 ml•min-1.The column temperature was 40 ℃.Result:The linearity was obtained from 1.004-5.020 μg(r=0.999 0).The average recovery was 98.82% with RSD=0.64%(n=6).Conclusion: The method is sensitive,simple,specific and accurate for determination of astragaloside in Tangshenkang granules.
