Objective: To establish HPLC-ELSD method for assay of astragaloside IV in Jianpi Yishen Capsules. Method: The content of astragaloside IV was determined by a HPLC method. The Diamonsil C18 (2) column was used. The mobile phase was acetonitrile-water (33: 67) with 1.0 mL·min-1 flow rate at 35℃. The temperature of drift tube for ELSD was set at 105℃
the air flow rate was 2.7 L·min-1. Result: The linear range of astragaloside IV was 1.985-11.91 μg (r=0.999 1). The average recovery was 102.0% (RSD 2.5%). Conclusion: The method is simple and quick. It can be used as determination method of astragaloside IV in Jianpi Yishen Capsules.
