The antioxidant characteristics of plant extracts of the family Lamiaceae in the Komi Republic

With use of biochemical methods and microbial test systems the antioxidant activity of extracts of plants of Lamiaceae family growing in the Republic of Komi is investigated. It is shown that antioxidant action of extracts is exhibited at the expense of direct inhibition of active oxygen forms, iron chelation and antioxidant genes induction. On models of genetically engineered strains Escherichia coli it is for the first time shown that their ability to activate OxyR-regulone genes and to influence the activity of RpoS-controlled system in conditions of oxidative stress is a considerable contribution in the antioxidant action.
