摘　　要：目的:对广玉兰果实中的脂肪酸成分进行研究。方法:采用索氏提取法从广玉兰果实中提取脂溶性成分,用气相色谱-质谱联用检测其化学成分。结果:从广玉兰中分离鉴定了12个脂肪酸成分和4个甾醇类成分,占色谱总馏分出峰面积的90.66%。主要为油酸(23.41%)、亚油酸(22.68%)、棕榈酸(16.29%)、硬脂酸(5.69%)、9,19-环羊毛甾-24-烯-3-醇(5.31%)、(3β)-9,19-环羊毛甾-24-烯-3-醇(1.06%)、(3β)-8,24-羊毛甾二烯-3-醇(8.89%)和22,23-二氢豆甾醇(2.24%)。结论:广玉兰果实中所含脂肪酸主要为不饱和脂肪酸,主要脂肪酸是油酸和亚油酸。Objective： To analyze the fatty acids from Magnolia grandifore. Methods： The fatty acids were extracted by Soxhlet extraction, and GC-MS was used to analyze their components. Results： Twelve fatty acids and four phytosterol were identified from M. grandifore, amounting to 90.66% of the total constituents. The main components are oleic acid （23.41%）, linoleicacid （22.68%）, palmitic acid （16.29%）, stearic acid （5.69%）, 9, 19-Cyclolanost-24-en-3-ol （5. 31%）, 3ff9, 19-Cyclolanost-24-en-3-ol （1. 06%）, 22, 23-dihydro- Stigmasterol （2.24%） and 3β-Lanosta-8,24-dien-3-ol （8.89%）. Conclusion： Unsaturated fatty acids were the main compounds in the fruit of M. grandifore, oleic acid and linoleic acid were the main fatty acids.
