高效液相色谱同时测定改善性功能和前列腺功能类保健食品13种非法添加药物

Simultaneously Detecting of 13 Illegally Added Drugs in Health Foods for Improving Sexual and Prostate Function by High Performance Liquid Chromatography

  • 摘要: 为了同时检测13种非法添加化学药物,建立适用于改善性功能和前列腺功能类保健食品的高效液相色谱分析方法。将样品经涡旋振荡1 min再甲醇超声提取10 min后,以甲醇-磷酸三乙胺缓冲液为流动相,经Agilent 5 HC-C18(2)色谱柱(250 mm×4.6 mm,5 µm)梯度分离,检测波长为218 nm和245 nm,柱温30 ℃,进样量10 μL。结果表明,该方法在线性范围内的相关系数(r)均大于0.999,检测限为0.76~4.61 mg/kg,平均回收率为92.4%~100.7%,相对标准偏差为0.44%~1.06%。运用本方法对65批次改善性功能或前列腺功能类保健食品进行筛查,结果在2批样品中检测出盐酸达泊西汀(分别为15.26 mg/片、6.34 mg/粒),1批样品中检测出盐酸育亨宾(10.12 mg/粒)。综上,该方法具有操作简单,灵敏度和准确度高,实用性强的特点,适用于改善性功能和前列腺功能的保健品中非法添加药物的日常监管检验。

     

    Abstract: To simultaneously detect 13 illegally added chemical drugs, a high performance liquid chromatography (HPLC) analytical method applicable to health food products for improving sexual function and prostate function was established. The samples were processed by vortex shaking for 1 min, followed by methanol extraction for 10 min under the ultrasonic condition. Then, the sample was separated on an Agilent 5 HC-C18 (2) column (250 mm×4.6 mm, 5 µm) with a gradient separation using methanol-phosphate-triethylamine buffer as the mobile phase. The detection wavelengths were of 218 nm and 245 nm, the column temperature was 30 ℃, and the sample size was 10 µL. Results showed that the correlation coefficients (r) in the linear range were all greater than 0.999, the detection limits were 0.76~4.61 mg/kg, the average recoveries were 92.4%~100.7%, and the relative standard deviations were 0.44%~1.06%. The method was applied to the rapid screening of 65 batches of health foods for improving sexual and prostate function, and results indicated that paroxetine hydrochloride was detected in 2 batches of samples (15.26 mg/tablet, 6.34 mg/pellet, respectively) and yohimbine hydrochloride was detected in 1 batch of samples (10.12 mg/pellet). In summary, the method is easy to conduct and characterized with high sensitivity and reliability, which is suitable for daily supervision and inspection of illegal added drugs in health foods for improving sexual and prostate function.
