Abstract

A number of amines were identified for the first time in grapes. These include methylamine, dimethylamine, ethylamine, diethylamine, n-propylamine, isobutylamine, a-amylamine, isoamylamine, pyrrolidine, and 2-phenethylamine. The trifluoroacetamides of the isolated amines were separated on Carbowax 20M or SE-54 fused silica capillary columns and identified by retention times and mass spectra. Two amines, diethyl and a-amyl, were identified in wine for the first time. Mass spectra of the pure TFA derivatives of these amines are given.
