Teor de fenóis e flavonoides, atividades antioxidante e citotóxica das folhas, frutos, cascas dos frutos e sementes de Piptadenia moniliformis Benth (Leguminosae – Mimosoideae)

Abstract

The total phenol and flavonoid content, in addition to the antioxidant and cytotoxic activities, of extracts and fractions of Piptadenia moniliformis was determined. This honey plant species is commonly known as "catanduba" or "angico de bezerro". The aqueous fraction derived from the peels of the fruits exhibited the highest antioxidant activity, remaining comparable to the standard value, and there was a general correlation between this activity and the phenol and flavonoid content. The antioxidant potential of this species provides a basis for future developments in herbal medicines and cosmetics. Only the hydro alcoholic extract, the dichloromethane fractions and the ethyl acetate fractions showed moderate cytotoxicity.
