Abstract
OBJECTIVE:To establish a method for simultaneous determination for ginsenoside Rb1,ginsenosides Rc,ginsen-osides Rb2 and ginsenosides Rd in Shengmai powder. METHODS:HPLC was performed on the column of Agilent ZORBAX Ex-tend-C18 with mobile phase of acetonitrile-0.1% formic acid(gradient elution) at a flow rate of 1.0 ml/min,wavelength was 203 nm,column temperature was 30 ℃ and the volume injection was 10 ml. RESULTS:The linear was 0.78-38.75 μg for ginsenoside Rb1(r=0.9996),0.51-25.50 μg for ginsenosides Rc(r=0.9996),0.43-21.50 μg for ginsenosides Rb2(r=0.9997)and 0.20-10.00 μg for ginsenosides Rd(r=0.9997);RSDs of precision,stability and reproducibility tests were lower than 2%;recoveries were 96.6%-101.2%(RSD=1.6%,n=6),97.0%-102.1%(RSD=1.7%,n=6),99.1%-102.8%(RSD=1.3%,n=6)and 96.3%-101.1%(RSD=1.6%,n=6). CONCLUSIONS:The method is simple,rapid with good stability,reproducibility and high precision,and can be used for quality control of Shengmai powder.关键词
