Abstract:Objective: To establish an HPLC method for determination ginsenoside RbI , Rg1 and Re in Ren shen lu. Method: The Angilent Zorbax ODS Cls columm (250 mm x4. 6 mm,5 tun) was used,the detection wavelength was 203 nm,the mobile phase consis- ted of acetonitrile-water,gradient elution the'flow rate was 1.0 ml.min-1, the column temperature was 27 ℃. Result: The linear ranges of ginsenoside RbI , Rg1 and Re were 1.0-10. 1μg,r =0. 999 8,1.0-10. 1 μg,r =0. 999 7 and 0. 69-6. 90 μg,r =0. 999 4;the average recoveries (n =5) were 99.7% (RSD 1.96% ). 99.9% (RSD 1.54% ) and 99. 5% (RSD 1.58% ) respectively. Conclusion: The method is simple and accurate,it can be used for quality control of Ren Shen Lu.
