中文摘要: 为比较广西壮族自治区内3个澳洲坚果主栽品种（桂热1号、OC、695）5个不同生长期（即盛花期后155、165、175、185、195 d）果仁的脂肪酸组分，利用气相色谱-质谱联用仪（gas chromatography-mass spectrometer，GC-MS）分析其脂肪酸组分。结果表明：澳洲坚果果仁不同生长期均检测出18种脂肪酸并且含有人体必需脂肪酸，其含量受品种及其生长的影响显著（P＜0.05），单不饱和脂肪酸（monounsaturated fatty acid，MUFA）的含量最高且遗传信息相对稳定；澳洲坚果果仁富含棕榈油酸，具有较高单不饱和脂肪酸/饱和脂肪酸值、多不饱和脂肪酸/饱和脂肪酸值和较低的致动脉粥样硬化指数、高胆固醇指数等特点。
Abstract:3 main varieties of macadamia （Guire NO.1，OC and 695）were mainly cultivated in Guangxi.Fatty acid components of 3 main varieties of macadamia kernels，harvested at 5 different growth stages（days after flowers 155，165，175，185，195 d）were analyzed by gas chromatography-mass spectrometry（GC-MS）.18 fatty acids were detected in macadamia kernels at different growth stages，including essential fatty acids，the content of which was significantly（P＜0.05）affected by both variety and stage of growth.Macadamia kernels were found to be rich in palmitoleic acid and high ratios of monounsaturated acid/saturated acid，polyunstaturated acid/saturated acid，and low values of atherogenic index，hypercholesterolemic index.
