Abstract: | A method for determination ginsedoside Re and Rh2 has been developed by RP-HPLC. Agilent Ex-tend C18(4.6 mm × 150 mm,5 μm)served as the stationary phase. The mobile phase consists of actonitrile and 0.05% acetic acid in term of gradient operation. Detection wavelength was 203 nm,column temperature 30.0℃,flow rate,1.00 mL/min. The analytical linearity range of ginsenoside Re and Rh2 were 0.17~456.6 mg/L and 6.00~449.4 mg/L,respectively .The recoveries of ginsenoside Re and Rh2 were 99.60% and 99.78%,respectively. The method developed is rapid,simple and accurate and can be used to determine the ginsenoside Re and Rh2 of Radix et Rhizoma Ginseng and Panax quinquefolium L extraction product. |
