Abstract

The genus Ipomoea is the most numerous in the Convolvulaceae family, with approximately 500-600 species, distributed mainly throughout South and Central America and Africa. Ipomoea species are used for medicinal, nutritional, ornamental and agricultural purposes. In popular medicine, species of the genus are used in the treatment of diabetes, hypertension, snake bites and fever. Even with a large number of species, until the present moment there are no studies regarding the antioxidant properties of the extracts of the leaves and flowers of Ipomoea species. Thus, the present study evaluated the antioxidant potential (DPPH and ABTS) of the ethanolic extracts of the leaves and flowers of Ipomoea carnea and Ipomoea alba. The species were collected on the campus of the Federal Rural University of Pernambuco. LC-MS analysis of the extracts of the leaves and flowers of I. alba revealed the presence of rutin, acacetin, luteolin, caffeic acid and p-coumárico acid. While in the extracts of the I. carnea were identified the caffeic acid, p-coumárico acid, luteolin, rutin, kaempferol and isoquercetin. DPPH test with extracts of leaves and flowers of the species of I. carnea revealed the Effective Mean Concentration (EC50) of 319 and 115 µg/mL, respectively. For the ABTS test, the extracts of the leaves and flowers of I. carnea presented values of EC50 = 317 and 215 µg/mL, respectively. The DPPH test with extracts of the leaves and flowers of the species of I. alba showed values of EC50 = 249 and 128 µg/mL, respectively. For the ABTS test, it was observed that the extracts of the leaves and flowers of I. alba were EC50 = 204 and 315 µg/mL, respectively. These results show that the extracts of the two Ipomoea species showed antioxidant properties.
