中文摘要：[目的]分析广西特色植物蒜头果(Malania oleifera)油脂中保健性脂肪酸的含量,探讨利用蒜头果种质资源开发保健油脂的价值。[方法]从广西巴马采集成熟蒜头果果实,取新鲜的蒜头果果仁,破碎并经冻干制成干粉,再用石油醚采用索氏提取法提取油脂,提取的油脂经硫酸-甲醇甲酯化后用GC-MS分析各种脂肪酸含量。[结果]蒜头果果仁油脂含量达65%(对果仁重);油脂中神经酸含量高达50.71%(占总脂肪酸);油酸和亚麻酸含量达36.56%。[结论]蒜头果油脂含有丰富的保健性脂肪酸,具有很高的利用价值,是生产保健油脂的极好资源。

外文摘要：[Objective] The aimwas to analyze the functional fatty acid composition in Malania oleifera fruit oil, discuss development and utilization value of germplasm resources. [ Method] Selecting mature fruit from Bama, Guangxi, nut of fresh fruit was smashed and lyophilized to make dry powder, and then the dried fruit powder was extracted with petroleum ether in a Soxhlet extractor. The oil was gained by distilling the solvent under reduced pressure from the extract. The extracted oil was transesterified by sulfuric acid and methanol. The fatty acid methyl es- ters of the oil were analyzed by GC-MS. [ Result] The results showed that the oil content was above 65% in the fruit nut. Particularly, the content of nervonic acid was special high reaching at 50.71% approximately; moreover, the content of oleic acid and linolenic acid reached to 36.56%. [ Conclusion] Malania oleifera oil contains abundant functional fatty acid with high utilization value, which is an excellent resource for production of functional edible oil.
