В этой статье освещается наиболее характерное свойство кверцетина растительного происхождения как антиоксидантного механизма действия. Кверцетин является самым мощным флавоноидом, который защищает организм от реактивных форм кислорода, образующихся при нормальном метаболизме кислорода или вызванных экзогенным повреждением. Лечебные свойства флавоноидов включают противовоспалительное (асептическое, противоаллергическое и др.) действие, а также антиоксидантное действие и соответственно нормализуют реактивность клеток и тканевой гомеостаз. Благодаря высокой эффективности переноса атомов водорода и электронов и прочной фиксации ионов металлов (ловушка металлов) дигидрокверцетин (ДГК) в качестве антиоксиданта защищает ткани от повреждения свободными радикалами.
