説明
The methyl eicosenoate, docosenoate, octadecatetraenoate, eicosapentaenoate and docosahexaenoate were isolated from the fatty acid methyl ester of skipper oil by urea fractionation, followed by vacuum fractional distillation.<BR>The process of the fractionations and the purity of each individual ester were checked by gasliquid chromatography.<BR>The structures of these acids were determined by oxidative ozonolysis with identification of the fragments (as benzyl and or methyl esters) by gas-liquid chromatographic analysis.<BR>These five acids were identified as : <BR>Δ9 eicosenoic acid<BR>Δ11 docosenoic acid<BR>Δ6, 9, 12, 15 octadecatetraenoic acid<BR>Δ5, 8, 11, 14, 17 eicosapentaenoic acid<BR>Δ4, 7, 10, 13, 16, 19 docosahexaenoic acid<BR>The procedure, benzyl-esterification followed by gas-liquid chromatography, may be available for semi-quantitative analysis of low molecular monobasic acids in water, for its simple process and fairly high yield (8090%).
