Abstract: Corn oil was extracted from corn in Liaoning. The fatty acids in the corn oil were estirified and analyzed by GC-MS. 8 fatty acids were separated and identified . Of them the major fatty acids were: hexadecanoic acid; 13-octadecenoic acid and 9,12-octadecadienoic acid. The content of 9,12-octadecadienoic acid in corn oil was determinated by HPLC.

Key words:  , corn oil; fatty acid; GC-MS; HPLC;
