摘 要:目的:建立测定乌贝益胃胶囊中5种蒽醌类衍生物(芦荟大黄素、大黄酸、大黄素、大黄酚和大黄素甲醚)含量的方法。方法:采用高效液相色谱法,Eclipse XDB C18色谱柱(4.6mm×150mm,5μm),流动相为甲醇-0.1%磷酸溶液(88:12),检测波长254nm,柱温30℃,流速1.0mL·min^-1。结果:芦荟大黄素、大黄酸、大黄素、大黄酚和大黄素甲醚5种成分进样量分另0在0.067~0.335Ixg(r=0.9996),0.070~0.351p,g(r=0.9998),0.068—0.341la,g(r=0.9999),0.070~0.348μg(r=0.9999),0.038~0.191μg(r=0.9997)与各自峰面积积分值呈良好的线性关系,平均加样回收率分别为97.95%(RSD0.98%),98.47%(RSD1.18%),98.00%(RSD0.71%),98.19%(RSD0.68%),96.26%(RSD1.35%)。结论:方法简便、准确、重复性好,可用于乌贝益胃胶囊的质量控制。Objective: To develop a high performance liquid chromatographic (HPLC) method for the determination of five anthraquinone derivatives (aloe-emodin, rhein, emodin, chrysophanol and physcion) in Wubei Yiwei capsules. Method: High performance liquid chromatography was perormed on an Eclipse XDB C18 (4. 6 mm × 150 mm, 5 μm) with methanol-0. 1% phosphoric acid (88: 12) as the mobile phase at a flow rate of 1.0 mL·min^-1, 254 nm as the detection wavelength, the temperature of column was at 30 ℃. Result: Five compounds showed good relationship at the range of 0. 067-0. 335 μg (r = 0. 999 6, for aloe-emodin) , 0, 070- 0.351 μg (r=0.999 8, for rhein), 0.068-0.341 μg (r=0.999 9, for emodin), 0.070-0.348 μg (r= 0. 999 9, for chrysophanol) , 0. 038-0. 191 μg ( r = 0. 999 7, for physcion) , the average recoveries were 97.95% (RSD 0.98%), 98.47% (RSD 1.18%), 98.00% (RSD 0.71%), 98.19% (RSD 0.68%), 96.26% (RSD 1.35% ). Conclusion: The results showed that the method is simple, accurate stable, and repeatable and it is suitable for quality control of Wubei Yiwei capsules.
