DART-MS快速检测中药材中非法染色物质金胺0

Identification of illegal addition of auramine 0 in chinese medicine by direct analysis in real time mass spectrometry

采用实时直接分析质谱法(DART-MS),建立了能直接对中药材及其饮片中非法添加金胺0快速进行定性的检测方法。在简单的样品预处理的情况下,方法检出限为50 ng,单个样品的检测时间不超过30 s。方法可用于中药材中金胺0的非法添加定性分析。

Direct analysis in real time ion source mass spectrometry was employed for fast detection of illegal additon auramine 0 in chinese medicines. Result shows that relatively high sensitivity has been obtained in the present study ,even though the simple pre-treatment for the samples was carried out. Limits of detection（ LOD ） was 50 ng/g. The average analysis time for each single sample was less than 30 seconds. DART-MS was proved to be a useful tool for rapid detection of illegal addition auramine 0 in chinese medicines. The method was simple, reliable, accurate, fast, and can be used for qualitative analysis of illegal to addition auramine 0 in chinese medicines.
