Abstract
Volatile fatty acids (VFA), alcohols, amines and carbonyl compounds which were produced from the 3-sn-phosphatidylcholine by autoxidation, were examined by gaschromatography and thin layer chromatography. On the VFA, amines and alcohols, the following compounds were characterized; acetic acid, iso-butyric acid, butyric acid, trimethylamine, ethanol, butanol, iso-amylalcohol, etc. The quantitative analysis of carbonyl compounds gave 87.0% of saturated and 13.0% of unsaturated carbonyls. The following compounds of saturated carbonyls were detected; n-ethanal (36%), n-propanal, n-butanal, n-hexanal, 2-pentanone and 2-nonanone. Though two fractions of unsaturated carbonyls could not be identified clearly by the reason of their unstability, one of them was considered to be 2-propenal (acrolein).
