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. |
