ANALYSIS OF CYANOLIPIDS AND TRIACYLGLYCEROLS FROM SAPINDACEAE SEED OILS WITH HIGH-TEMPERATURE GAS-CHROMATOGRAPHY AND HIGH-TEMPERATURE GAS-CHROMATOGRAPHY CHEMICAL-IONIZATION MASS-SPECTROMETRY

The seed oils of three Sapindaceae species have been examined by high- temperature gas chromatography using glass capillary columns coated wi th the stationary phases SOP-50 (50% diphenyl-50% dimethylpolysiloxane , methoxy-terminated) and OV-225-OH (25% phenylmethyl-25% cyanopropylm ethylpolysiloxane, hydroxy-terminated), respectively. The cyanolipid a nd triacylglycerol fraction could be identified by a combination of hi gh-temperature gas chromatography with a flame ionization and a nitrog en-phosphorus detector and gas chromatography-mass spectrometry in pos itive and negative chemical ionization mode using NH3 and CH4/N2O as r eagent gases. The OV-225-OH phase showed better separation properties than the SOP-50 phase and up to 34 peaks could be separated. The analy sis of the fatty acids in the seed oil of Allophylus edulis as their m ethyl esters by high-resolution GC and GC-MS are presented for the fir st time. (C) 1997 Elsevier Science B.V.
