目的 建立柔肝降脂胶囊中橙黄决明素、芦荟大黄素、大黄酚和大黄素甲醚的HPLC测定方法。方法 采用Waters Symmetry C₁₈色谱柱（250 mm×4.6 mm，5 μm）；流动相为甲醇–0.1%磷酸水溶液，梯度洗脱；检测波长288 nm；体积流量为1.0 mL/min；柱温30℃；进样量10 μL。结果 橙黄决明素、芦荟大黄素、大黄酚、大黄素甲醚的线性范围分别为1.59～51.00、0.87～27.92、1.63～52.17、0.22～7.06 μg/mL。平均回收率分别为97.55%、100.40%、98.75%、101.30%，RSD值分别为1.93%、1.53%、1.77%、2.23%。4种蒽醌类成分中橙黄决明素和大黄酚的质量分数较高，大黄素甲醚的质量分数较低，不同批次柔肝降脂胶囊样品中芦荟大黄素的质量分数差异较明显。结论 所建立的方法可用于柔肝降脂胶囊中4种蒽醌类成分的测定，可为柔肝降脂胶囊的质量控制研究提供参考。

Objective To establish HPLC method for determination of aurantio-obtusin, aloe-emodin, chrysophanol, and physcion in Rougan Jiangzhi Capsules.Methods The HPLC analysis was performed on Waters Symmetry C₁₈ column（4.6 mm×250 mm, 5 μm）with methanol - 0.1% phosphoric acid solution by gradient elution. The detection wavelength was set as 288 nm, flow rate was 1.0 mL/min, the column temperature was 30 ℃, and the sample volume was 10 μL. Results The linear ranges of aurantio-obtusin, aloe-emodin, chrysophanol, and physcion were 1.59 — 51.00, 0.87 — 27.92, 1.63 — 52.17, and 0.22 — 7.06 μg/mL. The recoveries were 97.55%, 100.40%, 98.75%, and 101.30% with values of 1.93%, 1.53%, 1.77%, and 2.23%, respectively. Among the four anthraquinones, the contents of aurantio-obtusin and chrysophanol were higher, but the contents of physcion were lower. The contents of aloe-emodin in different batches of Rougan Jiangzhi Capsules samples were significantly different. Conclusion The HPLC method established can determinate the contents of four anthraquinones in Rougan Jiangzhi Capsules, which can provide reference for the quality control research of Rougan Jiangzhi Capsules.
