摘　　要：采用气相色谱、胰脂酶水解法分析了文冠果油脂肪酸组成和Sn-2位脂肪酸分布,油脂脂肪酸组成中不饱和脂肪酸含量接近90%,油酸、亚油酸含量75.5%以上;Sn-2位脂肪酸中不饱和脂肪酸为97%,其中油酸、亚油酸含量较高(95.0%).高效液相色谱、Rancimat仪测定结果表明:文冠果油中维生素E含量为51.24 mg/100g;氧化稳定性值在110℃时为4.24 h;碘值为111.9 g/100g,为半干性油脂;文冠果仁中粗脂肪含量达62%、粗蛋白为29%以上,是一种珍贵的木本油料.The article analyzed the composition and Sn-2 position fatty acid distribution of Xanthoce sorbifolia Bunge oil by using gas chromatography and pancreas lipase hydrolysis. The fatty acids contained unsaturated fatty acid up to 90%, in which oleic acid and linoleic acid were more than 75.5%; the Sn-2 position fatty acids contained unsaturated fatty acid 97%, in which oleic acid and linoleic acid were 95%. Through HPLC and Rancimat determination, the results showed that the Xanthoce sorbifolia Bunge oil contained vitamin E 51.24 mg/100g; the duration of the oxidation stability at 110 ~C was 4.24 hours; the iodine value was 111.9 g/100g; and the Xanthoce sorbifolia Bunge oil was semi-drying oil. The Xanthoce sorbifolia Bunge seed contained crude fat 62% and crude protein above 29%, and is a previous woody oil plant.
