Their relative contents were determined by area normalization. Results showed 29 kinds of aroma components were identified in the grape. According to the relative content, the first five components were dibutyl phthalate (17.77%); 1, 2-Benzenedicarboxylic acid. diisooctyl ester (8.25%); 2-furaldehyde (7.10%); 3, 7-Octadiene-2, 6-diol, 2, 6-dimethyl. (5.53%) and oleic acid (4.50%), respectively; 31 kinds of aroma components were identified in the dry red wine, and the first five components of wine were Phenylethyl Alcohol (26.78%); Thiophene, tetrahydro-2-methyl- (12.04%); Octanoic acid, ethyl ester (7.02%); 1, 3-Butanediol (5.20%); Hexanoic acid, ethyl ester (4.55%), respectively.
