摘要：

The constituent cutin acids of apple cuticle have been determined by preparative TLC of the methyl esters followed by combined gas chromatography-mass spectrometry of the TMSi ethers of the methyl esters. This method may be applied to small amounts of cutin and has allowed the detection of a variety of hitherto unreported cutin acids. The principle cutina cids are 10,16-dihydroxyhexadecanoic acid, threo and erythro-9, 10,18-trihydroxyoctadecanoic, 16-hydroxyhexadecanoic, 18-hydroxyoctadec-9-enoic and 18-hydroxyoctadeca-9,12-dienoic. The location of the double bonds in the unsaturated compounds was determined by a novel method involving hydroxylation followed by GC-MS of the trimethylsilyl ethers of the resulting vic-dihydroxy compounds. © 1968.
