Розроблено простий, швидкий і чутливий спектрофотометричний метод для визначення загальної антиоксидантної активності рослинних препаратів і випробувано його на семи багатокомпонентних дієтичних добавках Фітосил, що містять лікарські рослини і кремнезем. Метод базується на відновленні забарвленного комплексaтетрабензо[b,f,j,n][1,5,9,13]тетраазациклогексадецинкупрум(II) нітрату природними антиоксидантами. Було показано, що загальна антиоксидантна активність біологічно активних добавок Фітосил строго корелює з загальним вмістом фенольних сполук (всі величини r2≥0.960), підтверджуючи, що фенольні сполуки є основними антиоксидантними компонентами в цих препаратах.

Ключові слова


лікарські рослини; антиоксидантна активність; комплекс двовалентної міді; загальний вміст фенольних сполук
