续随子油脂肪酸组成分析

Fatty acid composition analysis of Euphorbia lathyris L. seed oil

通过索氏抽提法测定续随子含油量,同时用气相色谱-FID法分析鉴定其油中各种脂肪酸组成及相对含量。结果表明,3个不同产区续随子含油量存在差异,分别为45.13%(安徽)、45.75%(河南)和43.66%(福建);主要脂肪酸为油酸,达83%以上。续随子油脂肪酸组成与理想柴油替代品的分子组成相类似,是我国发展生物柴油的理想原料。

The oil content of Euphorbia lathyris L. seed was detected by Soxhlet extraction method, and fatty acid composition of the oil was analyzed by gas chromatography - FID mehod. The results showed that the oil content of Euphorbia lathyris L. seed from different origins, such as Anhui, Henan and Fujian,is 45.13% ,45.75% and 43.66% ,respectively. The main fatty acid of the seed oil is oleic acid which is over 83%. The fatty acid composition of Euphorbia lathyris L. seed oil is similar to that of the ideal material used to produce biodiesel and the seed oil could be developed widely as an ideal feedstock of biodiesel in China.
