| 为开发利用云南核桃资源，对云南8个主栽核桃品种仁中神经递质类成分（色氨酸、5-羟基色氨酸、5-羟色胺、褪黑素）、油脂中脂肪酸及内源性抗氧化成分（β-胡萝卜素、角鲨烯、β-谷甾醇和生育酚）含量进行测定，采用主成分分析对8个主栽核桃品种进行相似性评价。结果表明：云南8个主栽核桃品种仁中色氨酸、5-羟基色氨酸、5-羟色胺、褪黑素含量分别为（0.02±0.00）～（008±0.01）mg/g、（11.40±0.83）～（38.84±1.38）μg/g、（2.99±0.62）～（12.31±1.01）mg/g、（3.95±0.55）～（19.00±1.47）ng/g；8个品种核桃油中不饱和脂肪酸含量为88.94%～92.67%，ω-6与ω-3多不饱和脂肪酸含量比值在5.32～13.29之间；8个品种核桃油中4种内源性抗氧化成分含量分别为β-胡萝卜素（7.21±0.30）～（17.30±0.20）μg/g、角鲨烯（319.41±5.43）～（1 293.00±13.00）μg/g、β-谷甾醇（214.29±4.00）～（382.86±6.49）μg/g、（α+γ）-生育酚（292.41±4.26)～(1 285.60±7.22）μg/g，生育酚含量较高的圆菠萝核桃油与娘青核桃油中的生育酚存在一定的促氧化风险。经主成分分析，云南8个主栽品种核桃按成分贡献值可分为4组，其中细香、娘青核桃为一组，三台、漾濞泡、大麻核桃为一组，大砂壳、大白壳核桃为一组，圆菠萝核桃单独为一组。综上，云南核桃富含多种营养成分，具有深度开发和利用价值。 |

| In order to develop and utilize the walnut resources in Yunnan, the contents of neurotransmitters (tryptophan, 5-hydroxytryptophan, 5-hydroxytryptamine, melatonin)in the kernels, fatty acids and endogenous antioxidant components (β-carotene, squalene, β-sitosterol, and tocopherol) in the oil of the eight major walnut cultivars in Yunnan were determined, and the similarity of the eight major cultivars in Yunnan was evaluated by using principal component analysis. The results showed that the contents of tryptophan, 5-hydroxytryptophan, 5-hydroxytryptamine and melatonin in kernels of eight major walnut cultivars in Yunnan were (0.02±0.00)-(0.08±0.01) mg/g, (11.40±0.83)-(38.84±1.38) μg/g, (2.99±0.62)-(12.31±1.01) mg/g, and (3.95±0.55)-(1900±1.47)ng/g, respectively. The unsaturated fatty acid content in eight major cultivars walnut oil was 88.94%-92.67%, and the ratio of ω-6 to ω-3 polyunsaturated fatty acid content in oil was 5.32-13.29. The contents of four endogenous antioxidant components in eight major cultivars walnut oil were β-carotene (7.21±0.30)-(1730±0.20) μg/g, squalene (319.41±543)-(1 293.00±13.00) μg/g, β-sitosterol (214.29±4.00)-(382.86±6.49) μg/g, (α+γ)-tocopherol (292.41±4.26)-(1 285.60±7.22) μg/g, and the tocopherol in the Yuanboluo and Niangqing walnut oil with higher tocopherol content had some pro-oxidant risk. After principal component analysis, the eight major walnut cultivars could be divided into four groups according to the contribution value of components. Among them, Xixiang and Niangqing walnut was a group, Santai, Yangbipao and Dama walnut was a group, Dashake and Dabaike walnut was a group, and Yuanboluo walnut was grouped separately. In conclusion, walnuts in Yunnan are rich in a variety of nutrients, and have the value of in-depth development and utilization. |
