采用索氏提取法提取桂花果实核仁中的油脂,通过GC-MS分析油脂中脂肪酸的组成及含量。结果显示,桂花果实核仁油脂中鉴定9种脂肪酸,主要包含油酸（39.04%）、亚油酸（33.15%）、棕榈酸（10.31%）、硬脂酸（3.80%）、9,12-十八二烯酸（4.62%）和γ-亚麻酸（6.44%）。其中油酸和亚油酸等不饱和脂肪酸含量高达83.25%。桂花果实核仁中油脂的不饱和脂肪酸含量高,具有良好的应用前景。

The oil was extracted from osmanthus seed by soxhlet extraction and the composition of fatty acids in this oil was analyzed by GC-MS. Nine kinds of fatty acids was identified by GC-MS. And main composition were as follow： oleic acid（39.04%）, linoleic acid（33.15%）, palmitic acid（10.31%）, stearic acid（3.80%）,（9E,12E）-9,12-octadecadienic acid（4.62） and gamma linolenic acid（6.44%）, in which the total content of unsaturated fatty acid is up to 83.25%.
