Abstract(s)
The purpose of this work was to study the volatile composition of vine leaves and vine
leaf infusion prepared from vine leaves collected at 30 and 60 days after grape harvest
of two Vitis vinifera L. species. Eighteen volatile compounds were identified by gas
chromatography–mass spectrometry in vine leaves and in vine leaf infusions. It was
observed that the volatile compounds present in vine leaves are dependent on the time
of harvest, with benzaldehyde being the major volatile present in vine leaves collected
at 30 days after harvesting. There are significant differences in the volatile composition
of the leaves from the two grape cultivars, especially in the sample collected at 60 days
after grape harvest. This is not reflected in the volatile composition of the vine leaf
infusion made from this two cultivars, the more important being the harvesting date for
the volatile profile of vine leaf infusion than the vine leaves grape cultivar.
