Various derivatization methods have been tested for their usefulness in determining the position of double bonds in a,band b,g-unsaturated isoprenoid acids by gas chromatography/electron ionization mass spectrometry.

Methylesters of polyenoic fatty acids (FAE) with up to six double bonds can be transformed to polyhydmxy derivatives by treatment with OsO 4. Under low energy electron impact the trimethylsilyloxy (O-TMS) derivatives of these polyenoic fatty acids exhibit mass spectro metric fragmentation patterns t
