【Abstract】 The rough fat in rape pollen was abstracted by Soxhlet extraction method with petroleum ether-ethyl ether mixed solvents, then methylated, and the methylated fatty acids were analyzed by GC-MS. Ten fatty acids were identified and their relative contents were determined by normalization method of area. The analyzed results exhibited that the unsaturated fatty acids content reached up to 76.0%, and polyunsaturated acids accounted for 53.2%.更多还原
