| 摘 要： | 采用索氏法提取杜仲种子中的粗脂肪，采用气相色谱及色谱- 质谱联用分析法测定杜仲种子中的脂肪酸组成及含量，利用氨基酸自动分析仪测定其氨基酸的组成及含量。杜仲种子油脂含量为35.5%，包括11 种脂肪酸，其主要成分为亚油酸(10.66%)、油酸(16.9%)、棕榈酸(6.03%)、硬脂酸(1.96%)、亚麻酸(63.15%)，以不饱和脂肪酸为主，含量高达91.26%，其中尤以亚麻酸含量最高，达63.15%；杜仲种子粗蛋白质含量为25%，主要氨基酸为Asp、Glu、Ser、Arg、Gly、Thr、Pro、Ala、Val、Met、I l e、Leu、Phe、 His、Lys、Tyr、Cys-Cys。其中必需氨基酸和半必需氨基酸含量较高，分别占氨基酸总量的33.6% 和11.2%。表明杜仲种子是一种有很高利用价值的可开发资源。

| Abstract: | Fatty acid and amino acid composition of Eucommia ulmoides Oliver seeds were analyzed using Soxhlet extraction followed by GC-MS and automatic amino acid analyzer,respectively.Eucommia ulmoides Oliver seeds comprised 35.5% oil and 11 fatty acids were identified in the oil,mainly including linolic acid (10.66%),oleic acid (16.9%),palmitic acid (6.03%),stearic acid (1.96%),and linolenic acid (63.15%),among which,unsaturated fatty acids were dominant with relative content as high as 91.26% and linolenic acid e... |
