Determination of Aflatoxins and Ochratoxins in Food by Liquid Chromatography/tandem Mass Spectrometry

, 2014
摘要 實驗以固相萃取法萃取水中及食品中之黃麴毒素與赭麴毒素，再以LC/MS/MS進行分離與偵測。以C18管柱進行分離，探討適當的動相比例，以梯度沖提方式，在21分鐘內可分離分析物；前處理方面，則分別探討不同固相萃取吸附材質、沖提溶劑種類與體積等因素對萃取效果之影響，找出最佳萃取條件，同時進行此方法之線性範圍、相關係數、偵測極限、精密度以及回收率之研究。最後將其應用於真實樣品中黃麴毒素與赭麴毒素之分析。 實驗結果顯示，以固相萃取法結合液相層析質譜儀，正離子電灑游離法選擇反應模式偵測(Selected
