| 中文摘要: |
| 对8种枣核（贡枣、晋枣、骨头枣、北樱枣、秤砣枣、敦煌大枣、滩枣、鸡心枣）油的脂肪酸组成与含量进行分析。结果表明：8种枣核油共检出24种脂肪酸，包括13种饱和脂肪酸、11种不饱和脂肪酸；饱和脂肪酸主要为棕榈酸、硬脂酸，不饱和脂肪酸主要为亚油酸、油酸、棕榈油酸；秤砣枣核油不饱和脂肪酸含量最高，达到84.55%；北樱枣核油、秤砣枣核油、滩枣核油和鸡心枣核油中油酸和亚油酸含量较高；贡枣核油、晋枣核油、骨头枣核油和敦煌大枣核油的棕榈酸含量较高；贡枣核油中亚麻酸含量最高，达到3.57%。采用聚类分析、主成分分析及线性判别分析，通过枣核油脂肪酸组成和含量可以实现8种枣核油的有效分类与区分，为不同品种大枣的分类判别与枣种质资源研究提供了新方法。 |
| 英文摘要: |
| Oils were extracted from eight jujube pits,including Gongzao, Jinzao, Gutouzao, Beiyingzao, Chengtuozao, Dunhuangdazao, Tanzao and Jixinzao,and the composition and content of fatty acids in the eight jujube pit oils were detected. The results showed that 24 fatty acids were found in jujube pits oils including 13 saturated fatty acids and 11 unsaturated fatty acids. Saturated fatty acids mainly included palmitic acid and stearic acid, and unsaturated fatty acids mainly included oleic acid, palmitoleic acid.The content of unsaturated fatty acids of Chengtuozao pit oil was the highest and reached 84.55%. The contents of oleic acid and linoleic acid in Beiyingzao, Chengtuozao, Tanzao and Jixinzao pit oils were higher,while the contents of palmitic acid were higher in Gongzao, Jinzao, Gutouzao and Dunhuangdazao pit oils. The linolenic acid in Gongzao pit oil was the highest, reaching 3.57%. Meanwhile, the class analysis, principal component analysis and linear discriminant analysis showed that the fatty acid composition and content of jujube pit oils could be used to discriminate jujube pit oils cultivars, providing a new method for the classification and discrimination of different varieties of jujube and the research of jujube germplasm resources. |
