Abstract:
In this study, we carried out the analyse of some polyphenolic fractions
obtained from a sample of red wine by solid-liquid repartition. The wine selected sample was
obtained by mixing noble wine varieties, with the purpose of realising a great concentration of
phenolic compounds. The fractions obtained from this special sample were firstly chemically
analysed (total quantity of polyphenols, total quantity of anthocyans, Folin-Ciocâlteu index and
permanganate index), and then were correlated with their specific effects on the intensity of
oxygen respiratory consumption of the batracian muscle and hepatic cells, carried out by the
Warburg micromanometrical method. Different biological effects (values of oxygen cellular
consumption) were recorded, according to the type of cells, composition of fractions
(polyphenol quantity) and duration of records. The obtained results evidenced a specific
influence of the studied fractions on the respiratory and energetic cellular processes, indicating
a series of useful pharmacological properties of some wine fractions.
