| 摘 要： | 采用索氏抽提法分别提取棕榈果肉和棕榈果仁中的油脂,以氢氧化钾—甲醇溶液对油脂进行甲酯化处理,用气相色谱-质谱(GC-MS)法分析。从棕榈果肉和棕榈仁的油脂中均分离并鉴定了9种脂肪酸,其中棕榈果肉中饱和脂肪酸质量分数为49.5%,主要有棕榈酸和硬脂酸,不饱和脂肪酸主要有油酸、亚油酸以及少量的亚麻酸和13,16-二十二碳二烯酸。棕榈仁中饱和脂肪酸80%以上,其中月桂酸质量分数达到41.5%,肉豆蔻酸和棕榈酸含量也较高,此外还含有少量的己酸、辛酸、癸酸和硬脂酸,不饱和脂肪酸有油酸和亚油酸。

| Abstract: | Palm oil and palm kernel oil were extracted by a soxhlet extractor,and esterfied with potassium hydroxide-methanol.The fatty acid compositions were determined by gas chromatography-mass spectrometry.Nine fatty acids were identified and quantified respectively.The relative content of saturated fatty acids from palm oil was 49.5 %,and existing forms were mainly palmitic acid and stearic acid.The unsaturated fatty acids were constituted of oleic acid,linoleic acid,linolenic acid and cis-13,16-docosadienoic acid.The relative content of saturated fatty acids from palm kernel oil was more than 80,and lauric acid had the highest content obtained with content of 41.5% among them.The other main compositions were myristic acid,palmitic acid,hexanoic acid,octanoic acid,capric acid and stearic acid.Oleic acid and linoleic acid constituted the unsaturated fatty acids. |
