| Abstract: | A new method was developed for the determination of cholesterol in food by GC/MS/MS. The cholesterol in sample was extracted with ethyl acetate. The determination was carried out using GC/MS/MS with molecular ion (m/z 386) of cholesterol as father ion and fragments (m/z386, m/z301, m/z231) as daughter ions for quantitative analysis. The method is of good linearity and high recovery. |
