摘　　要：为探讨采用GC-MS对腰果种仁中的脂肪酸分析的可行性。利用索氏提取法提取腰果种仁中的脂肪酸,经甲酯化处理后,采用气相色谱-质谱(GC-MS)联用技术对所得脂肪酸进行成分分析和鉴定。结果共分离出16种化合物,占脂肪酸总量的99.84%。腰果种仁主要的脂肪酸成分为油酸38.02%,亚油酸39.66%,棕榈酸6.45%,棕榈油酸3.13%,硬脂酸3.09%,亚麻酸4.34%。The fatty acids in seeds of Anacardium occidentale L. were extracted by Soxhlet extraction were identified by GC-MS after been esterified to discuss the feasibility of analyzing the fatty acids in seeds of Anacardium occidentale L. by GC-MS. The results showed that 16 compounds were isolated and identified, which was 99.84 % of the total fatty acids. The composition of fatty acids in seeds of Macadamia spp. included 9-octadecenoic acids （38. 02%）, 9, 12-octadecadienoic acid （39. 66%）, palmitic acid （6. 45;）, 9-hexadecenoic acid（3.13%） ,octadecanoic acid（3.09%） ,and linolenie acid（4.34%）.
