【摘要】 目的建立养颜丸中2,3,5,4’-四羟基二苯乙烯-2-O-β-D-葡萄糖苷的含量测定方法。方法采用高效液相色谱法,使用十八烷基硅烷键合硅胶柱,流动相为乙腈-水(25∶75),检测波长320nm。结果在色谱实验条件下,2,3,5,4’-四羟基二苯乙烯-2-O-β-D-葡萄糖苷在0.05～0.40mg/mL范围内线性关系良好,r=0.9999;平均加样回收率为99.7%,RSD=0.31%(n=9)。结论该方法操作简便、快速、准确。更多还原

【Abstract】 Objective To establish an HPLC method for the determination of 2, 3, 5, 4’-teterahydroxystibene-2-O-β-D-glucoside in Yangyan Pills. Methods HPLC was carried out on a C18 column, using mobile phase of acetonitril-water(25 ∶ 75), and detection wavelength was 320nm. Results The 2, 3, 5, 4’-teterahydroxystibene-2-O-β-D-glucoside sample showed a good linear relationship at the range of 0.05～ 0.40 mg/mL, r=0.999 9. The average recovery was 99.7 % (n=9), and RSD was 0.31 % (n=9). Conclusion The method was simple, available and accurate.更多还原
