RESUMO

OBJECTIVE:To establish an HPLC method for the determination of Diosgenin in Bixiefenqing pills.METHODS:The samples were separated on DiamonsilTM C18(200 mm?4.6 mm,5 ?m)column.The mobile phase consists of acetonitrile-water(92∶8) at a flow rate of 1.0 mL?min-1.The detecting wavelength was set at 203 nm and the column temperature was set at 35 ℃.RESULTS:The linear range of Diosgenin was 0.115 36~1.038 24 ?g(r=0.999 9).The average recovery was 98.71%(RSD=1.92%,n=9).CONCLUSION:The method was proved to be simple and accurate,and suitable for the identification and quality control of Bixiefenqing pills.
