云南地区麻疯树籽种仁化学成分测定

Determination of Chemical Elements in Jatropha curcas Seeds Collected from Different Areas of Yunnan Province

测定云南不同产地麻疯树籽种仁各种化学成分含量,对相关数据进行比较分析。结果表明:生长地不同,麻疯树种子中各化学成分具有一定差异,种仁中油脂含量为46%～58%,粗蛋白含量为20%～28%,总糖含量为1.6%～2.9%,灰分含量为4.1%～4.9%;微量元素含量在不同样地间存在较大的差异,华坪地区种子中各微量元素含量均高于其他样地。综合来看:潞江地区的种子含油率最高,是制备生物柴油的优质种植基地;云南地区麻疯树籽的各营养成分含量较高,去脂脱毒后有望成为动物饲料源。

The contents of different chemical components of Jatropha curcas seeds collected from different production areas in Yunnan Province were determined,and the relevant data were comparatively analyzed.The results showed that there were some differences in the contents of chemical components in the seeds sampled from different production areas.The oil contents varied between 46% to 58%;the crude protein content changed from 20% to 28%;the total sugar content varied from 1.6% to 2.9% and the ash content changed from 4.1% to 4.9%.The contents of microelements changed greatly among the different production areas.The content of each microelement in the seeds collected from Huaping area was generally higher than that of sampled from other areas.Comprehensively speaking,the oil content in the seeds grown in Lujiang area was the highest,which would be the superior quality provenance for bio-diesel manufacturing.The nutrient contents of the J.curcas seeds produced in Yunnan Province were comparatively higher,the seeds would be consumed as animal feedstuffs after de-fatting and detoxification.
