摘要
目的:建立以反相高效液相色谱法测定神曲胃痛胶囊中大黄素、大黄酚含量的方法。方法:色谱柱为Phenomenex BDS~C18(250mm×4.6mm,5μm),流动相为乙腈一水一冰醋酸(55:45:0.5),流速为1.0mL·min^-1,检测波长为254nm。结果:大黄素、大黄酚的检测浓度分别在2.188~54.700、4.312~107.800μg·mL^-1范围内与各自峰面积积分值呈良好的线性关系(r均为0.9999);二者平均回收率分别为96.52%、98.45%,RSD分别为0.59%、0.43%。结论:本方法简便、可靠、重现性好,可用于神曲胃痛胶囊的质量控制。
OBJECTIVE: To determine the contents of Emodin and Chrysophanol in Shenqu weitong capsule by RPHPLC. METHODS: The samples were separated on Phenomenex BDS- C18(250 mm × 4.6 mm, 5μm) .The mobile phase consisted of acetonitrile-water-glacial acetic acid (55 : 45 : 0.5) at a flow rate of 1.0 mL · min^-1. The detection wavelength was set at 254 nm. RESULTS: The linear range for Emodin was 2.188-54. 700μg · mL^-1(r = 0.999 9) and 4.312-107. 800 μg · mL^-1 for Chrysophanol (r = 0.999 9) . The average recovery of Emodin was 96.52% (RSD = 0.59%) versus 98.4,5% (RSD = 0.43% )of Chrysophanol. CONCLUSION: This method is convenient, accurate, reproducible and applicable for the quality contro; of Shenqu weitong capsule.
