Determination of Prim-O-glucosylcimifugin in Biyan Tablets by HPLC / 中药新药与临床药理

ABSTRACT

Objective To establish the determination of prim-O-glucosylcimifugin in Biyan Tablets by HPLC.Methods The HPLC determination was carried out on Diamonsil C18 column(4.6 mm? 250 mm,5 ? m).The mobile phase consisted of methanol-acetonirile-H2O(181270) with a flow rate of 1.0 mL/min,and the ultraviolet detection wavelength was set at 254 nm.Results Prim-O-glucosylcimifugin showed a good linearity in the range of 0.1888～ 1.534 ? g with the peak area score,the coefficient was 0.9997,and the average recovery was 101.74 %(RSD=2.97 %).Conclusion The method is accurate and reliable,and can be used for the quality control of Biyan Tablets.
