Abstract:

【Objective】 To study the characteristics of volatile organic compounds (VOCs) in leaves of three walnut varieties, compare the differences of VOCs among leaves of each walnut, and construct the scent fingerprint of VOCs of three walnut varieties.【Methods】 Gas chromatography-ion mobility spectrometry GC-IMS was used to analyze the odor fingerprints of volatile substances in the leaves of Hickory walnut, Wen185 and American red walnut, and variance analysis and principal component analysis were used to analyze the differences in the fingerprints of volatile substance odor in their leaves. 【Results】 The volatile substances were contained in the leaves of different walnut varieties including alcohols, esters, aldehydes, terpenes and a small amount of ketones and furans. The contents of ethyl acetate, β-pinene dimer and acetone in walnut were significantly different from those of Wen185. The contents of 2-vinylaldehyde, cineole and 2, 5-dimethylfuran in walnut were higher than those of Wen185 and American red walnut. 【Conclusion】 There are significant differences in the fingerprint profiles of Hickory walnut, Wen185 and American red walnut, and the content of alcohol was higher in Hickory walnut, and the content of terpenes was higher in American red walnut. The content of Wen185 in esters was higher than that of Hickory walnut and American red walnut.

摘要:

【目的】 研究挥发性有机物在3个核桃品种叶片中的特性,比较各核桃叶片之间挥发性物质差异程度,构建3个核桃品种挥发性有机物气味指纹图谱。【方法】 用气相色谱-离子迁移谱技术(gas chromatography ion mobility spectrometry GC-IMS)分析山核桃、温185和美国红核桃叶片中挥发性物质气味指纹图谱,利用方差分析法、主成分分析法,分析其叶片中挥发性物质气味指纹图谱差异。【结果】 不同核桃品种叶片中含有的挥发性物质包括醇类、酯类、醛类、萜烯类及少量酮类和呋喃类物质。3个核桃品种之间挥发性成分差异较大,在美国红核桃中的乙酸乙酯、β-蒎烯二聚体和丙酮挥发性物质含量与温185有较大差异,在山核桃中2-乙烯醛、桉叶油醇及2,5-二甲基呋喃含量较高且与温185和美国红核桃有较大差异。【结论】 山核桃、温185、美国红核桃所呈现的指纹图谱有明显差异,且醇类在山核桃中含量较高,萜烯类在美国红核桃中含量较高;温185在酯类中含量与山核桃和美国红核桃较高且有差异。
