摘要:

目的:建立高效液相色谱法同时测定益母草中丁香酸、阿魏酸、芦丁、大豆素、槲皮素、橙皮素、山柰酚和芹菜素8 种有效成分的方法。方法:采用InertSustain C18(150 mm×4.6 mm,5 μm)色谱柱;流动相为甲醇(A)-0.1%乙酸溶液(B);线性梯度洗脱;流速1.0 mL/min;紫外检测波长285 nm;柱温35 ℃;进样量20 μL。结果:该条件下8 种成分的分离度良好,标准曲线在线性范围内呈良好线性,相关系数均不小于0.999 1(n=7)。加样回收率(n=3)平均值为89.93%~102.01%,相对标准偏差为1.17%~3.11%。结论:实验结果表明本方法简单、快速、准确,为药用植物益母草的质量控制提供了实验依据。

Abstract:

Objective: To establish a high performance liquid chromatography (HPLC) method for the simultaneous
determination of syringic acid, ferulic acid, rutin, daidzein, quercetin, quercetin, quercetin and quercetin in Herba Leonuri.
Methods: The analytes were separated on an InertSustain C18 (150 mm × 4.6 mm, 5 μm). The mobile phase consisted of
methanol and 0.1% acetic acid (pH 3.0) with gradient elution at a flow rate of 1.0 mL/min. The UV detection wavelength
was set at 285 nm. The column temperature was maintained at 35 ℃. The injection volume was 20 μL. Results: The eight
compounds were well separated, showing good linear correlations with correlation coefficient (r) ≥ 0.999 1 (n = 7). The
average recoveries were 89.93%–102.01%, with relative standard deviations (RSDs) between 1.17% and 3.11%. Conclusion:
The method is simple, rapid and accurate, which can provide an experimental basis for quality control of Herba Leonuri.
