| Summary: | The aim of this work is mainly to determine the effect of some pedoclimatic conditions on
the phenolics composition of wine originated from Cabernet Sauvignon red grape variety, cultivated
in the region of Drǎgǎşani area (Romania) during 2013-2016. The obtained results revealed that the
higher temperatures decrease the quantities of phenolic compounds, especially that of anthocyanins.
Also, the more abundant precipitations lead to the decrease of these compounds, constituting a
stress factor for their biosynthesis. Total polyphenol concentrations range from 1478 mg GAE/L to
2949 mg GAE/L. Anthocyanins are the most abundant class of polyphenols in wines and among
these malvinidin derivatives predominate. Also, a close relationship between phenolic subclasses and
antioxidant activity was observed for the wine samples. |
