Objective To obtain high levels of unsaturated fatty acid, especially of alpha linolenic acid content. Methods Using unsaturated fatty acid iodine value as response value, the response surface me-thodology was applied to optimize the enrichment of unsaturated fatty acid from Eucommia seed oil by urea adduction fractionation. The content of alpha linolenic acid was analyzed by GC-MS. Results The expe-rimental results showed that the ratio of fatty acid, urea and 95% alcohol was 1:3:9.8, adducting tempera-ture was?21.8℃and adducting time was 13 h. Under this condition, the unsaturated fatty acid iodine value was 289.67 g/100 g and the content of α-linolenic acid reached 85.41%. Conclusion Extracting unsatu-rated fatty acid by urea inclusion method is effective, and the content of alpha linolenic acid can be im-proved.
