A fast and sensitive reversed high performance liquid chromatographic（HPLC） method was developed for the simultaneous detection of three ginsenosides,ie.Rg1,Re and Rb1 in Chinese herbal residues.Effects of solvent,temperature,solvent matrix ratio and time on extraction efficiency were investigated.The sample was ultrasonically extracted with 10 times liquid of 70% methanol at 40 ℃ for 05 h.Chromatographic separation was performed on a Zorbax SB-C18（46 mm×150 mm,5 μm） column by gradient elution using water-acetonitrile as mobile phase at a flow rate of 10 mL/min.The injection volume was 20 μL,the column temperature was 20 ℃ and the detection wavelength was 203 nm.External calibration of peak area versus concentration was used for the quantitation.There were excellent linearities for ginsenosides Rg1，Re and Rb1 in the ranges of 1874-25761,3748-46854 and 388-9693 mg/L,respectively，with their correlation coefficients all above 0999.The limits of quantitation（LOQ,S/N=10） for Rg1,Re and Rb1 were 1769,1394 and 114 mg/L,respectively.The average recoveries at three spiked levels were in the range of 891%-107%,with relative standard deviations（RSD,n=3） of 06%-41%.The method was applied in the detection of ginsenosides Rg1，Re and Rg1 in Chinese herbal samples with simplicity,rapidness and high sensitivity.
