Abstract:
OBJECTIVE:To establish a method for the contents determination of astragalosidesⅠ,Ⅱ,Ⅲ,Ⅳ,lobetyolin and for-mononetin in Shenqi fuzheng injection. METHODS:HPLC was performed. The detector was evaporative light scattering detector, column was Ultimate XB-C18 with mobile phase of acetonitrile-0.5% formic acid (gradient elution) at a flow rate of 1.2 ml/min, column temperature was 30 ℃,and injection volume was 10 μl. RESULTS:The linear range was 0.62-5.67 μg for astragalosidesⅠ(r=0.999 6),0.78-6.31 μg for astragalosidesⅡ(r=0.999 6),0.36-3.48 μg for astragalosidesⅢ(r=0.999 7),0.81-6.72 μg for as-tragalosides Ⅳ(r=0.999 5),0.82-7.03 μg for lobetyolin(r=0.999 8)and 0.58-6.62 μg(r=0.999 7)formononetin;limit of quan-titation was 1.21,0.15,0.12,0.03,0.12,0.17 μg/ml;limit of detection was 0.35,0.35,0.04,0.01,0.03,0.04 μg/ml;RSDs of pre-cision,stability and reproducibility tests were lower than 2%;recoveries were 95.1%-101.1%(RSD=2.0%,n=9),95.2%-100.7%(RSD=1.9%,n=9),95.8%-100.2%(RSD=1.4%,n=9),96.2%-100.6%(RSD=1.7%,n=9),96.6%-101.2%(RSD=1.4%, n=9) and 95.9%-99.5%(RSD=1.2%,n=9),respectively. CONCLUSIONS:The method is simple and accurate,and can be used for the simultaneous determination of astragalosidesⅠ,Ⅱ,Ⅲ,Ⅳ,lobetyolin and formononetin in Shenqi fuzheng injection.
