摘要
目的:用高效液相色谱法测定胃苏颗粒中橙皮苷和柚皮苷的含量。方法:采用DiamonsilTMC18(4.6 mm×150mm,5μm)色谱柱;乙腈-磷酸水(pH=3.5)(22:78,V/)为流动相,流速为1.2 mL/min;.检测波长为283 nm。结果:待测组分与其他组分分离度良好(R>1.5),橙皮苷和柚皮苷线性范围分别为0.25～1.49μg和0.093～0.56μg,橙皮苷和柚皮苷的平均回收率分别为99.2%,98.8%,RSD分别为1.6%,2.3%。结论:高效液相色谱法是测定胃苏颗粒中橙皮苷和柚皮苷成分的一种简便、有效的方法。
The content of hesperidin and naringin in Stomach Su Keli was determinated by HPLC. Column is DiamonsilTMcls（4.6 mm × 150 mm, 5 μm）. The mobile phrase is CHzCN- pH 3.5 H3PO4 = 22 ： 78（V/V）. The velocity of flow is 1.20 mL·min-1 and the detective wavelength is 283 nm. The experimental results show that the separate degree of the undeterminated components and others is favourable （R 〉 1.5 ）, the linearity tangs of the content of hesperidin and naringin are from 0.25 to 1.49 μg ·mL^-1 and 0.093 to 0.56 μg·mL^-1, respectively. The average recoveries of hesperidin and naringin are 99.2% and 98.8% and theirRSDs are 1.6% and 2.3%, respectively. HPLC is a convenient and effective method to determine the content of hesperidin and naringin in Stomach Su Keli.
