Abstract :	[en] In the present study, fatty acids from Hedera helix L. are identified and measured. After epoxidation, monoenic fatty methyl esters (81.6 %) of the total fatty acids) are separated by mean of very resolutive capillary columns with cyanopropylsiloxane stationnary phase. ldentification are achieved with the help of GC-MS. Electron impact and more conveniently chemical ionisation (NHi are both used. Observation of characteristic mass fragments from fatty epoxides allow us to identify three octadecenoic positionnal isomers . petroselinic acid (C 1 8. 1 delta 6 cis), oleic acid (C18:1 delta 9 cis) and vaccenic acid (C18:1 delta 11 c i s ) . This last one i s rare in vegetable o i l s .
