Fig. 6. Selected-ion current chromatogram obtained from GC/negative ion chemical ionization/MS analysis of IsoFs (Top) and F2-IsoPs (Middle) formed during oxidation of arachidonic acid in vitro. (Bottom) The deuterated internal standard ([2H4]15-F2t-IsoP). Compounds were analyzed as pentafluorobenzyl ester, TMS ether derivatives with selected-ion monitoring of the M – 181 ion (loss of •CH2C6F5).
