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 Agua Doce, Campos Novos and Tangara were determined using spectrophotometric and chromatog. 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 quant. results showed that the most important volatile compounds for wine aroma were esters, fatty acids, 1-hexanol and 2-phenylethanol alcs., and C13-norisoprenoids β-damascenone and α-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. This study involved multiple reactions and reactants, such as Isopentyl hexanoate (cas: 2198-61-0Application In Synthesis of Isopentyl hexanoate).
Isopentyl hexanoate (cas: 2198-61-0) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
