Identification of aroma compounds of Vitis vinifera L. flowers by SPME GC-MS analysis

Abstract

Using a gas chromatographic method (GC-MS- analysis), it was possible to determine the volatile con- stituent of an odorous flower from Vitis vinifera varie- ties growing in Sicily. More than 50 compounds were identified and the technique allowed us to determine that sesquiterpenes, as well as monoterpenes such as limonene and cymene, were the principal components. The odour-profiles allowed us to distinguish between variety groups or even single varieties.
