摘要
目的:建立中成药与保健食品中非法添加20种降糖类化学成分的快速测定方法。方法:采用液相色谱-串联质谱法(LC-MS/MS),以Sunfire^(TM) C_(18)(100 mm×2.1 mm,5.0μm)为分析柱,流动相采用乙腈-0.1%甲酸(75:25),电喷雾电离(ESI)、多反应监测(MRM)扫描方式,对中成药、保健食品中非法添加的20种化学成分进行快速定性定量分析。结果:建立了快速分离检测中成药、保健食品中20种非法添加成分的测定方法,检测限低于20 ng。结论:该方法专属性强、灵敏度高,适用于降糖类中成药、保健品中非法添加成分的定性定量分析。
Objective： To establish a liquid chromatography-tandem mass chromatography （LC-MS/MS） method for the simultaneous screening 20 anti-diabetic chemical components in health care food and Chinese traditional patent medicine. Method： This method involved liquid chromatography-tandem mass spectrometry,with SunfireTM Cms cotumn （ 100 mm ×2. 1 mm,5.0 μm）. The mobile phase consisted of 0. 1% formic and acetonitrile （25：75）. The target compounds were analyzed with LC-MS/MS-ESI. Multiple-reaction monitoring （MRM） was used to screen 20 chemical components in health care food and Chinese traditional patent medicine. Result： A fast and sensitive liquid chromatography mass spectrometric （LC/MS） method for the simultaneous screening of 20 chemical components was described. The detection lowest limit of these substances was below 20 ng. Conclusion： The method is sufficiently selective and sensitive to detect chemical components in health care food and Chinese traditional patent medicine.
