[The influence of ion metal on flavonoid radioprotection activity towards yeast cells]

Influence of ion Mn2+ and Fe2+ on ability of flavonoids intercept free radical and reveal radioprotection activity towards yeast cells was investigated. In work have been used flavonols quercetin, rutin and anthocyanins allocated of flowers Hibiscus. As a measure of radiating damage of cages of yeast the exit of ions K+ served. It is shown that Fe2+ ions essentially reduce protection activity flavonoids, and the ions of manganese showing protection properties, at presence anthocyanins sensibilization radiation damage.
