Abstract: AIM: To establish the determination of ginsenoside R e and R g1 in Compound Jiangtang Oral Liquid(Radix Ginseng, Fructus Schisandrae Chinensis, Radix Rehmannia, Radix Asparagi, etc.) by HPLC. METHODS: C 18 ODS was used as a stationary phase, acetonitrile-0.05% phosphoric acid (96∶400) as a mobile phase and detection wavelength at 203nm. RESULTS: The linear range of ginsenoside R e concentration was from 0.66 to 3.29?g?mL -1 and correlation coefficient was 0.9991, the linear range of ginsenoside R g1 concentration was from 1.05 to 5.27?g?mL -1 and correlation coefficient was 0.9998. The average recovery of sample was 98.2% and RSD 2.2% ( n =5), respectively. CONCLUSION: The method is simple and convenient, accurate with a good reproducibility and can be used for determination of ginsenoside R e and R g1 in Compound Jiangtang Oral Liquid.
