The objective of this work was to evaluate the phytochemical profile and the antioxidant activity comparing the results between different organs of Costus spicatus. We used the stems, leaves and flowers of Costus spicatus harvested at the State University of Norte Fluminense "Darcy Ribeiro" in the city of Campos dos Goytacazes, Rio de Janeiro, Brazil. The different organs were evaluated for antioxidant activity and phytochemical profile in the hexane, ethyl acetate and butanol fractions. The results obtained proved the presence of triterpenes and steroids (Liebermann-Burchard), flavonoids (Shinoda), saponins (foaming index), alkaloids (Dragendorff) and tannins (ferric chloride). We demonstrated the potential antioxidant activity. We concluded that Costus spicatus presented all classes of metabolites studied, among which some already have their biological activity known by the literature, being necessary the performance of quantitative and research studies that demonstrate their pharmacological effects, thus contributing to the development of new drugs.
