不同地区麻疯树籽油的理化性质及脂肪酸组成 . Physicochemical properties and fatty acid composition of Jatropha curcas seed oil in different areas

Abstract

The seeds of Jatropha curcas were collected from six different areas.The characteristics of J.curcas seed were studied,the physicochemical properties and fatty acid composition of J.curcas seed oil were also analyzed.The results showed that the characteristics of J.curcas seed from different areas were not significant discrepancy,the variation coefficients of seed length,width and lateral diameter was 2.6%,1.2% and 2.4%,respectively,the variation coefficient of a thousand seed weight was much larger,which reached 3.8%;all of oil content of the seeds were over 30% and the main fatty acid composition were C16 and C18;the contain of unsaturated fatty acid of J.curcas seed oil was high,all of them were over 70%.
