摘 要 目的:建立同时测定经典名方三化汤中柚皮苷、橙皮苷、新橙皮苷、芦荟大黄素、大黄酸、羌活醇、大黄素、和厚朴酚、异欧前胡素、厚朴酚、大黄酚、大黄素甲醚等12种成分含量的方法。方法:采用高效液相色谱(HPLC)-多波长切换法。色谱柱为COSMOSIL C18,流动相为乙腈-0.1%磷酸溶液(梯度洗脱),流速为1.0 mL/min,检测波长分别为280 nm(柚皮苷、橙皮苷、新橙皮苷)、254 nm(芦荟大黄素、大黄酸、大黄酚、大黄素甲醚)、310 nm(羌活醇、大黄素、和厚朴酚、异欧前胡素、厚朴酚),柱温为30 ℃,进样量为10 μL。结果:12种成分的分离度均较良好,阴性对照无干扰。柚皮苷、橙皮苷、新橙皮苷、芦荟大黄素、大黄酸、羌活醇、大黄素、和厚朴酚、异欧前胡素、厚朴酚、大黄酚、大黄素甲醚分别在55.4~5 540、3.8~380、45.6~4 560、1.2~120、2.1~210、2.2~220、2~200、2.4~240、0.8~80、1.2~120、1.7~170、1.1~110 μg/mL质量浓度范围内与其峰面积的线性关系良好(R 2≥0.999 6);检测限分别为0.064、0.024、0.053、0.018、0.020、0.041、0.050、0.091、0.030、0.180、0.028、0.083 μg/mL,定量限分别为0.213、0.075、0.174、0.060、0.063、0.138、0.166、0.323、0.130、0.600、0.094、0.275 μg/mL;精密度、稳定性(24 h)和重复性试验的RSD均小于2%(n=6);平均加样回收率分别为99.54%、99.69%、100.01%、99.93%、100.36%、99.65%、100.03%、100.47%、99.97%、100.68%、99.90%、100.17%,RSD均小于2%(n=6)。结论:本研究所建立的HPLC-多波长切换法操作简便、专属性强、稳定性好,可用于三化汤中柚皮苷、橙皮苷、新橙皮苷等12种成分含量的同时测定。

ABSTRACT   OBJECTIVE: To establish a method for simultaneous determination of 12 components including naringin, hesperidin, neohesperidin, aloe emodin, rhein, notopterol, emodin, honokiol, isoimperatorin, magnolol, chrysophanol and physcion in classical formula Sanhua tang. METHODS: HPLC-multi-wavelength switching technology was adopted. The determination was performed on COSMOSIL C18 with mobile phase consisted of acetonitrile-0.1% phosphoric acid (gradient elution) at the flow rate of 1.0 mL/min. The detection wavelength was 280 nm (naringin, hesperidin, neohesperidin), 254 nm (aloe emodin, rhein, chrysophanol, emodin methyl ether), 310 nm (notopterol, emodin, honokiol, isoimperatorin, magnolol). The column temperature was set at 30 ℃, and the sample size was 10 μL. RESULTS: A total of 12 components were well separated without negative interference. The linear range of naringin, hesperidin, neohesperidin, aloe emodin, rhein, notopterol, emodin, honokiol, isoimperatorin, magnolol, chrysophanol and physcion were 55.4-5 540, 3.8-380, 45.6-4 560, 1.2-120, 2.1-210, 2.2-220, 2-200, 2.4-240, 0.8-80, 1.2-120, 1.7-170, 1.1-110 μg/mL (R 2≥0.999 6), respectively. The detection limits were 0.064, 0.024, 0.053, 0.018, 0.020, 0.041, 0.050, 0.091, 0.030, 0.180, 0.028 and 0.083 μg/mL, respectively. The limits of quantitation were 0.213, 0.075, 0.174, 0.060, 0.063, 0.138, 0.166, 0.323, 0.130, 0.600, 0.094 and 0.275 μg/mL, respec-    tively. RSDs of precision, stability (24 h) and repeatability tests were all lower than 2% (n=6). Average recoveries were 99.54%, 99.69%, 100.01%, 99.93%, 100.36%, 99.65%, 100.03%, 100.47%, 99.97%, 100.68%, 99.90%, 100.17% (all RSDs were lower than 2%,  n=6), respectively. CONCLUSIONS: Established HPLC-multi-wavelength switching technology is simple, specific and stable, which could be used for the simultaneous determination of 12 components in Sanhua tang as naringin, hesperidin, neohesperidin.
