| Abstract: | The sample of the Gymnocypris Przewalskii Pazewalskii (Kessler) Oil was extracted with a mixed solvent of ether and n - hexane.The extracts were esterified withmethanol - potassium hydroride method. Then fatty acid esters were separated and determined by capillary gas chromatography. Fifteen kinds of fatty acids have been identified. The major components are palmitic acid,palmitolic acid,oleic acid.linolenic acid,eicosapentaenoic acid and docosahexenoic acid. |
