Conteúdo:

In Brazil, wine-growing regions of high altitude have been evaluated for the cultivation of grapes destined for the production of quality
wines. In this study the phenolic content, the volatile compounds profile and the in vitro antioxidant activity of samples produced
in Água Doce, Campos Novos and Tangará were determined using spectrophotometric and chromatographic techniques. A total of
95 volatile compounds were identified in the samples analyzed, of which borneol is reported in Brazilian Merlot wines for the first
time. The quantitative results showed that the most important volatile compounds for wine aroma were esters, fatty acids, 1-hexanol
and 2-phenylethanol alcohols, and C13-norisoprenoids &#946;-damascenone and &#945;-ionone. The phenolic content observed was comparable
to the results obtained for Merlot red wines from other regions in Brazil and in other countries. Also, the wine samples were effective
in capturing the free radicals DPPH and ABTS.
