| 中文摘要: |
| 以山西地区的10个品种核桃为原料，通过溶剂浸提法提取核桃油，分析核桃油的脂肪酸和生育酚组成及含量。结果表明：品种对核桃油中不同脂肪酸含量有不同程度的影响，油酸含量的变异系数最大（变异系数23.32%），顺-11-二十碳烯酸含量变异系数最小（变异系数5.84%）；10种核桃油中均未检出β-生育酚，‘金薄香1号’γ-生育酚含量最高，为356.44 mg/kg，‘辽宁2号’γ-生育酚含量最低，为227.63 mg/kg，‘晋龙1号’α-生育酚含量最高，为13.49 mg/kg，‘辽宁2号’α-生育酚含量最低，为8.87 mg/kg；通过聚类分析，得出‘金薄香1号’和‘西林3号’均为高γ-生育酚以及高总生育酚品种；通过主成分分析，得出‘晋龙1号’综合得分最高，‘辽宁2号’综合得分最低。‘晋龙1号’、‘西林3号’、‘晋龙2号’和‘金薄香1号’的综合性状较好，适合在山西地区重点推广。 |

| Ten varieties of walnuts in Shanxi were used as raw materials, the walnut oils were obtained by solvent extraction. The compositions and contents of fatty acid and tocopherol of ten walnut oils were analyzed. The results showed that cultivars had different effects on the content of different fatty acids in walnut oils. The variation coefficient of oleic acid was the highest, reaching 23.32%, and the variation coefficient of cis-11-icosenoic acid was the lowest, reaching 5.84%. In addition, β-tocopherol was not detected in these walnut oils. The γ-tocopherol content of Jinboxiang No.1 was the highest, reaching 35644 mg/kg, and the γ-tocopherol content of Liaoning No.2 was the lowest, reaching 22763 mg/kg. The α-tocopherol content of Jinlong No.1 was the highest, reaching 13.49 mg/kg, and the α-tocopherol content of Liaoning No.2 was the lowest, reaching 8.87 mg/kg. By cluster analysis, cultivars with high γ-tocopherol and total tocopherol content included Jinboxiang No.1 and Xilin No.3. Through principal component analysis, the comprehensive score of Jinlong No.1 was the highest, while Liaoning No.2 was the lowest．The comprehensive characters of Jinlong No.1, Xilin No.3, Jinlong No.2 and Jinboxiang No.1 were better and suitable for planting in Shanxi. |
