This work describes the antioxidant activity evaluation and determination of polyphenols of ethyl acetate (EtOAc) and dichloromethane (CH2 Cl2 ) fractions of the leaves of Ipomoea cairica L. Sweet, a plant belonging to the family Convolvulaceae. This species is popularly known as corda­de­viola and is used in Brazilian folk medicine as anti­inflammatory and antirheumatic. The antioxidant activity was determined by DPPH and each fraction was the IC50 calculated. The IC50 showed values of 43.06 µg/mL for CH2 Cl2 fraction and 45.43 µg/mL for the EtOAc fraction. The polyphenol content was determined using the patterns pyrogallic and gallic acids. From this work was not possible to establish a positive relationship between amount of phenolics compounds and antioxidant activity performed by ethyl acetate and dichloromethane fractions. Both showed similar DPPH front, but distinct in the quantification of phenolics compounds.
