烤烟品种中烟特香301烤后烟叶石油醚提取物分析

Analysis of Petroleum Ether Extracts from the Characteristic Fragrant Fluecured Tobacco Variety Zhongyantexiang301

摘要

摘要: 为进一步明确特征香韵烤烟品种中烟特香301与中烟100香韵差异的物质基础，采用气质联用技术对二者中部烟叶的石油醚提取物进行测定，并进行了主成分分析（PCA）和偏最小二乘-判别分析（PLS-DA）。结果表明，中烟特香301和中烟100烤后烟叶石油醚提取物中各鉴定到99和98种化合物，其中共有化合物87种，中烟特香301和中烟100各自特有化合物12和11种。中烟特香301的酯类、酸类、醇类、酮类、烯类和醛类化合物的相对含量均高于中烟100，共有化合物中，二者含量差异化合物有29种，二氢猕猴桃内酯、巴伦西亚橘烯、香叶基芳樟醇、巨豆三烯酮等28种成分的含量显著高于中烟100。该结果为揭示中烟特香301香韵风格形成的物质基础提供了参考。

Abstract: In order to further clarify the material basis of the aroma difference between the special flavor flue-cured tobacco variety Zhongyantexiang301 and Zhongyan100, the petroleum ether extracts of their middle leaves was determined by GC-MS, and principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) were carried out. The results showed that 99 and 98 compounds were identified in the petroleum ether extracts of flue-cured tobacco leaves of Zhongyantexiang301 and Zhongyan100, including 87 common compounds. Zhongyantexiang301 and Zhongyan100 have 12 and 11 unique compounds, respectively. The relative contents of esters, acids, alcohols, ketones, olefins and aldehydes of Zhongyantexiang301 are higher than those of Zhongyan100. Among the common compounds, there are 29 compounds with different contents between them. and the contents of 28 components, such as dihydrokiwifruit lactone, valencia orangeene, geranyl linalool, and megadjatrienone, were significantly higher than those of Zhongyan100. The results provide a reference for revealing the material basis for the formation of the flavor style of Zhongyantexiang301.
