Resumo: Pereskia aculeata Miller, popularly known as ora-pro-nóbis is a cactaceae native to the American continent. In Brazil, the species can be found in the Northeast and Southeast regions. This non-conventional food plant is recognized by the nutritional value of its leaves, due to the high content of minerals like iron as well as being rich in proteins. The leaves are also used as ingredients for the preparation of culinary recipes. However, there are not many studies on bioactivity and antioxidant capacity of the fruits of ora-pro-nóbis. Therefore, the objective of this study was to determine the presence of bioactive compounds and an antioxidant capacity in the peel and pulp of the fruit of ora-pro-nóbis. The fruits was acquired from the Experimental Station of Embrapa Inorganic Agrobiology in Seropédica/RJ, they were harvested manually in the mature stage (yellow coloring) and transported to the Laboratory of Instrumental Analysis of the UFRRJ`s Institute of Technology, for further analysis. The parameters evaluated was compounds bioactive, such as total carotenoids, vitamin C, yellow flavonoids, total anthocyanins, phenolic compounds and capacity antioxidants (DPPH and FRAP). The ora-pro-nóbis peel presented higher mean values for total carotenoids (3.02 mg / 100 g), yellow flavonoids (12.33 mg / 100 g), total anthocyanins (1.35 mg / 100 g), total phenolics (138, 82 mg GAE / 100 g), DPPH (1598.93 ?mol TE / 100 g) and FRAP (5377.13 ?mol TE / 100 g), while the pulp conferred is higher at mean values for vitamin C content (23 , 58 mg / 100 g). The fruits of ora-pro-nobis presented high content of bioactive compounds and antioxidant activity. This is demonstrates that an ora-pro-nóbis could be a potential source with functional and mercadological appeal. Even so, new studies must be conducted to the fruit of the species and related to the best detailing and understanding of the functional and/or nutraceuticals compositions. The value added of your products is important as it is targeted at the consumer and your products are just as important as those aimed at human health.
