The results of an experimental work on grapes (Vitis vinifera L.) variety ‘Aleatico’, regarding ethylene and 1-methylcyclopropene (1-MCP) treatments are reported. Total polyphenols, characteristic anthocyanins and volatile compounds, are represented in this paper. Aleatico grapes were harvested at 20.6% of SSC (soluble solids content) and 2.5 g L-1 of acidity and then treated with 500 ppm of ethylene and/ or 0.5 ppm of 1-methylcyclopropene. The spectrophotometric results of total phenols and athocyanins and HPLC determinations for qualitative assay are significant in order to demonstrate the influence of the treatments. Especially malvidin-3-glucoside, delphinidin and petunidin-3-monoglucoside are stimulated by ethylene treatment. Volatile compounds analysis reveal a significant effect of the gaseous treatments on the content of some typical esters.
