2020
Chemistry, Technology and Application of Substances
The antioxidant activity (AA) of various extracts of grape marc (Vitis vinifera L.) was studied. Radical absorption activity (RAA) was calculated in reactions with DPPH+ and ABTS•+ radicals and AA in rat liver homogenate by two markers of oxidative stress (OS): contents of thiobarbiturative products and carbonyl groups of proteins.
