ABSTRACT
OBJECTIVE:
A HPLC-ELSD method was developed for determination of the content of astragaloside Ⅳ in Xin'an granules.METHODS:
The separation was performed on Kromasil ODS C18 column(150 mm?4.6 mm,5 ?m) with the mobile phase consisted of acetonitrile-water(35∶65).The temperature of the drift tube was 40 ℃ and the flow rate of gas(air) was 2.1 L?min-1.RESULTS:
The linear range of astragaloside Ⅳ was 1.32~7.95 ?g(r=0.998 9) and the average recovery was 97.84(RSD=1.01%,n=9).CONCLUSION:
The method is simple,accurate and reproducible,and it can be used for the quality control of Xin'an granules.
