摘 要:目的:建立RP—HPLC法测定保健食品中3种蒽醌衍生物含量。方法:以XTerra^TM RP18(3.9mm×150mm,5μm)为色谱柱,流动相:甲醇+含0.5%冰醋酸水溶液(75+25),检测波长:270nm,流速:1ml/min,柱温:25℃,外标法定量。结果:同时测定3种蒽醌衍生物大黄酸、大黄酚、大黄素的含量,其浓度分别在5.4~54、7.5-75和8.8~88μg/ml范围内呈良好的线性关系。方法的平均回收率分别为:107.3%、99.7%、101.1%,RSD为4.2%、6.8%、7.3%。结论:该方法简便、快速,测定结果准确可靠,重现性好,可用于保健食品中蒽醌含量的测定。Objective:To establish a RP- HPLC method for simultaneous determination of three kinds of anthraquinone derivatives in Health foods. Methods:Anthraquinone derivatives were determined by HPLC using XTerraTM RPls (3.9 mm×150 mm, 5 μm) ,0. 5% acetic acid - methanol (25 -75) ,detective wave 270 nm,flow rate 1 ml/min and column temperature 25℃. Results: The linearity of Rhein, Chrysophanol, Emodin were good in the range of 5. 4 - 54,7.5 - 75 and 8.8 - 88 μg/ml. The average recovery of Rhein was 107.3%, Chrysophanol 99.7%, Emodin 101.1%. Relative standard deviations (RSD) of them were 4. 2% ,6. 8% ,7.3%. Condusion: This method is simple, rapid, accurate and reproducible for detection of anthraquinone in Health foods.
