| Chemical constituents of the volatile compounds from the dry red wine of Cabernet Sauvignon fermented by the grapes from 3 different terrains were studied.The aromatic compounds were extracted by solvent extraction and analyzed by GC-MS,and their relative contents determined by area normalization.The result shows that the main types and relative contents of aromatic compounds of the wine of low altitude terrain are superior to the wine of high altitude terrain,and Hexanoic acid,ethyl ester,1-Hexanol,2-ethyl-,Indole-3-ethanol were only detected in the former;the wine of the plain is inferior to that of low altitude terrain,but esters relative content is higher than that of hilly terrain;Phenylethyl Alcohol,Butanoic acid,3-methyl-,ethyl ester were not found in the wine of high altitude terrain. |
