野漆树种籽含油率与脂肪酸成分分析

以中国野漆树、昭和福野漆树、伊吉野漆树等3种野漆树种籽为试材对象,利用索氏提取法和气相色谱-质谱联用法,测定了野漆树的含油率和脂肪酸成分。结果表明,(1)3种野漆树的含油率分别为12.37%,、6.46%、11.22%,差异极显著;(2)3种野漆树种籽油中脂肪酸成分至少有26种,其中亚油酸、油酸(E)、油酸(Z)、亚麻酸、棕榈油酸、棕榈酸、硬脂酸等7种脂肪酸的含量总和分别占测定到总脂肪酸含量的97.35%、97.92%、98.16%;(3)3种野漆树种籽油中不饱和脂肪酸与饱和脂肪酸差别较大,为73.08%~84.46%之间,最高差值达11.38%;(4)昭和和伊吉两个日本品种的野漆树与中国野漆树在12-羟基-油酸、环丙烯丁酸、亚麻酸(异构)、蓖麻醇酸(蓖麻油酸)、二十二烷酸、二十三烷酸、二十四烷酸、9-十八碳烯酸十四酯、月桂酸等9种脂肪酸中存在质的区别。
