Determination of the unknown components of pecan kernel oil

Using gas chromatography-mass spectroscopy (GC-MS) method, 14% unknown components and contents in pecan oil were determined for the first time. The results showed that the unsaturated fatty acid content of pecan kernel oil was 89.0%, and 13 kinds of unknown components such as nonadecaol, 8-hexyl-pentadecane, 10-methyl-eicosane, 11, 14- eicosadienoic acid, 1-bromo-8-heptadecyne, 9-hexyl-heptadecane, tetracosane, 13-docosenoic acid, 1-bromo-7-nonadecyne, 15-tetracosenoic acid, hexacosanoic acid, 7-hexyl-eicosane and heptacosane were detected. Among these components, 13-decosenoic acid, 15-tetracosenoic acid and nonadecanol have medical value and stronger physical activities.
