This study was undertaken to determine the fatty acid composition of Monthong durian (Durio zibethinus, Murr.) clones. The extract of Monthong Thai durian was analyzed by 1H NMR and combined gas chromatography and mass spectrometry (GC-MS). The GC-MS data were used to identify 15 methyl esters of the durian extract after transesterification using sodium in methanol. The most prominent components found were 9-octadecenoic acid(Z) methyl ester (26.22%), cholest-5-en-3-ol(3.beta) (24.95%), vitamin E (15.40%), hexadecanoic acid methyl ester (6.37%), 9,12-octadecenoic acid(Z,Z) methyl ester (5.88%), 9-octadecenoic acid(E) methyl ester (5.00%) and ethyl oleate (4.08%). The 1H NMR data, signals for a methoxy group of transesterification oil at δ 3.60-3.75 was readily discernible.
