摘 要:目的:建立高效液相色谱(HPLC)法测定玉叶清火胶囊中穿心莲内酯、脱水穿心莲内酯的含量的方法。方法:采用HPLC法测定,ODS—C18(250mm×4.6mm,5μm)色谱柱,流动相为甲醇-水(55:45);检测波长:225nm,流速为1.0ml·min^-1。结果:穿心莲内酯在0.24~2.40峭范围内线性关系良好(r=0.9999);平均回收率99.79%,RSD%为1.0%(n=5)。脱水穿心莲内酯在0.18~0.90μg范围内线性关系良好(r=0.9996);平均回收率98.50%,RSD%为1.04%(n=5)。结论:该方法操作简单,重现性好,适用于玉叶清火胶囊的质量控制。Objective: To establish HPLC method for determination of andrographolide and dehydroandrographolide in Yuyeqinghuo capsule. Method: HPLC method was used, the chromatography consisted of ODS - C18 (250 mm ×4.6 mm, 5 μm) chromo bar with mobile phase of methanol - water(55 : 45 ) at the detection wavelength of 225 nm, the flow rate was 1.0 mlomin - 1. Result: Andrographolide showed a good linear relationship at the range of 0.24 ~ 2.40 μg(r = 0. 9999 ) ; The average recovery was 98.50% with RSD% 1.04% (n = 5). Conclusion: This method is simple to manipulate with good reproducibility, so it is fit for quality control to Yuyeqinghuo capsule.
