西南部分地区麻疯树种子油的理化性质及脂肪酸组成分析

Physicochemical Characteristics and Fatty-acid Composition of Seed Oil of Jatropha curcas from Southwest China

从西南6个地区采集了麻疯树种子并分析比较了其生物学性状和种子油的理化性质及脂肪酸组成．所有样品的百粒重范围为41．80-71．39g，出仁率60．02％-81．43％，种仁含油率51．76％-57．93％，种子含油率31．07％-47．17％，不饱和脂肪酸含量74．89％-79．68％．其中永胜产麻疯树的种子品质最好，其出仁率为81．43％，种仁含油率57．93％，种子含油率47．17％，不饱和脂肪酸含量79．68％．攀枝花和宁南产麻疯树的种子品质次之．双柏和罗甸麻疯树的种子油酸值为0．81，在所有样品（0．81-9．46）中最低．对麻疯树种子及种子油性质的相关数据进行方差分析，结果表明，产地不同，麻疯树种子的生物学性质、种子油理化性质和脂肪酸组成都有一些差异．

The seeds of Jatropha curcas L. were collected from 6 different locations in Southwest China and their biological characteristics were studied. The physicochemical characteristics and fatty acid composition of the seed oil were also analyzed. The results showed that the hundred-seed-weight ranged from 41.80 g to 71.39 g, the kernel weight of seed from 60.02% to 81.43%, the oil content from 51.76% to 57.93% in kernel and from 31.07% to 47.17% in whole seed, and the total unsaturated fatty acid from 74.89% to 79.68% of all seed samples. The seed produced from Yongsheng was found the best, and its kernel weight was 81.43% , with oil from kernel 57.93% and oil from whole seed 47.17% , and total unsaturated fatty acid 79.68%. The seeds from Panzhihua and Ningnan were also good. Among all the seed samples （ acid value ranged from 0.81 to 9.46） , the acid value of the seeds from Shuangbai and Luodian was the lowest, that was, 0.81. Variance analysis was done for the data of the seed and oil of J. curcas. The results indicated that there were differences in the biological characteristics of J. curcas seeds, and the physicochemical characteristics and fatty acid composition of its seed oil in different locations.
