Objective To establish a HPLC method for the simultaneous determination of 6 kinds ective ingredients,of ginsenosides Rg1,Re,Rb1,Rd,paeoniflorin and paeonol,in the extracts of Ginseng and Cortex Moutan compounds group. in the effective compounds group of Radix Ginseng and Cortex Moutan. Methods The detection was carried out on SHIMADZU C18 column(150 mm×4.6 mm,5 μm) with the mobile phase consisting of acetonitrile -water in gradient elution mode at 35 ℃ and at the flow rate of 1 mL·min-1. The UV detection wavelength was set at the maximum absorption wavelength,203 nm for ginsenosides Rg1,Re,Rb1 and Rd,230 nm for paeoniflorin,and 274 nm for paeonol.The injection volume was 10 μL. Results The linear ranges of ginsenosides Rg1,Re,Rb1,Rd,paeoniflorin and paeonol were 1.90~11.40 μg(r=0.9990),0.995~5.97 μg(r= 0.9994),1.575~9.45 μg(r=0.9998),1.62~9.72 μg(r=0.9999),1.57~9.42 μg(r=0.9990),4.56~27.36 μg(r=0.9999),respectively. The average recovery was 101.10 % for ginsenoside Rg1(RSD=1.80 %,n=6),98.49 % for ginsenoside Re(RSD=2.72 %,n=6),100.14 % for ginsenoside Rb1(RSD=1.94 %,n=6),99.23 % for ginsenoside Rd(RSD=2.50 %,n=6),100.45 % for paeoniflorin(RSD=2.40 %,n=6) and 100.20 % for paeonol(RSD=0.64 %,n=6). Conclusion The established method is simple,rapid and accurate with good repeatability and stability,and is suitable for the quality control of effective compounds group of Radix Ginseng and Cortex Moutan .
