Study of the antioxidant activity of rowan extracts (Sorbus aucuparia) by biotesting method

Abstract

Special importance in modern unfavorable environmental conditions is given to nutrition, which should ensure the weakening of the negative effect of harmful eco-factors on the human body, contribute to increasing its protective and adaptive capabilities, and, as a result, reduce the risk of developing various pathologies. At the same time, it should be taken into account that the diet of a modern person should be rich in biologically active components that can exhibit antioxidant properties. Recently, scientists are increasingly considering plant extracts as sources of antioxidants. Among them, a special role is assigned to Sorbus aucuparia, whose antioxidant activity is described as comparable, or even higher than other fruits. The article presents data on the study of the antioxidant activity of water extracts of mountain ash by biotesting. The antioxidant activity was evaluated using a biological model – Paramecium caudatum, determining the stress resistance of infusoria to hydrogen peroxide. The study revealed an increase in the stress resistance of Paramecium caudatum infusoria when adding extracts of mountain ash to the nutrient mixture compared to the control.
