摘要
用乙醚抽提栾树种油 ,将样品皂化和甲酯化后 ,用毛细管质谱 -色谱法(GC -MS)测定了栾树种油的脂肪酸组成 ,共鉴定出21种成分,其不饱和脂肪酸相对含量为88 % ,主要成分为二十碳烯酸和亚油酸 ,它们的相对含量分别为44.98 %和39.75 %。
An oil was extracted from seed of Koelreuteria paniculata Laxm. with ethyl ether. After saponification and esterification the oil was determined by GC-MS with capillary column. 21 fatty acids have been identified and their relative contents were determined by area normalization. The index of unsaturation for the oil is 88%. Eicosenoic acid and linoleic acid are chief components, and their relative contents are 44.98% and 39.75%, respectively.
