【摘要】 目的:测定垂阴茶糖浆中岩白菜素的含量。方法:采用反相高效液相色谱法,色谱柱:VP-ODS(150 mm×4．6 mm,5μm),流动相:甲醇-水(15:85);检测波长:275 nm;流速:1．0 ml·min-1;柱温:室温。结果:岩白菜素的线性范围0．25～2．52μg,r=0．999 9,平均回收率为98．76％,RSD％=1．3(n=6)。结论:该法适用于测定垂阴茶糖策中岩白菜素的含量。更多还原

【Abstract】 Objective:To set up a RP-HPLC method for the determination of content of Bergenin in Chuiyincha syrups. Method: The VP-ODS column(150 mm×4.6 mm,5μm) was used. The mobile phase consisted of methanol-water (15:85), and the detection wavelength was at 275nm. Result:The linear range of Bergenin was 0.25 - 2.52μg(r = 0.999 9). The average recovery was 98.8%,RSD = 1.3% (n = 6). Conclusion:The method can be used for the determination the content of Bergenin in Chuiyincha syrup.更多还原
