Analysis of the Content of Nonvolatile Organic Acids in Different New Flue-cured Tobacco Varieties

In order to explore the contents of nonvolatile organic acids in different flue-cured tobacco varieties, we used thirteen tobacco varieties as experimental materials to determine the contents of their leaf nonvolatile organic acids, including Yunyan 87, Yunyan 100, Yunyan 108, Yunyan 112, Yunyan 116, AOV405, AOV506, AOV708, DVH301, DVH2001, DVH2103, PVH19 and NC71 under plot design experiment. The results showed that the contents of multiple organic acids from high to low were malic acid, oxalic acid, citric acid and malonic acid in a flue-cured tobacco variety. The contents of senior fatty acids reduced as linoleic acid, stearic acid, palmitic acid, myristic acid and lauric acid with carbon atoms reduction of saturated carbon chain. The contents of nonvolatile organic acids in different varieties from high to low were NC71, PVH19,AOV708, Yunyan108,Yunyan87,Yunyan 116,DVH301,Yunyan100,AOV506,AOV405,Yunyan112,DVH2001,DVH2103, the contents of nonvolatile organic acids in different flue-cured tobacco varieties and its components existed many differences. This research provides the basis for more comprehensive grasping at the tobacco characteristics and the screening of suitable tobacco varieties of cigarette industrial enterprise preference.
