摘要
目的:建立高效液相色谱法测定止泻片中穿心莲内酯含量。方法:采用高效液相法,色谱柱为C18柱,流动相为乙腈:水(35:65),流速1.0ml/min,检测波长为225nm。结果:在2.31~9.10μg线性范围内。穿心莲内酯的线性关系良好,平均回收率为100.26%。结论:方法简便、灵敏、准确、样品处理简便易行,可作为穿心莲制剂中的质量控制方法。
Objective:To determine the content of Andrographolide in Zhixiepian by HPLC. Methods: We used HPLC method, with C18as the chromatographic column and CH3CN:H2O as the mobile phase (35: 65) with the flow rate of 1.0ml/min and the wavelength of 225nm. Results: Good linearity was obtained in the range of 2.31~ 9. 10μg, The linear regression equation is y = 138638.80x - 38785.82 and RSD 0.74%. The average recovery could reach 100. 26%. Conclusion:The method is proved to be simple, accurate and reproducible. It can be used in the determination of Andrographolide in Zhixiepian.
