Cashew (Anacardium occindetale L.) is native of the Northeast brazilian and its production is concentrated in the states of Piauí, Ceará and Rio Grande do Norte. The cashew apple is known for its antioxidant potential related to its phytochemical compounds such as vitamin C, carotenoids and phenolic compounds (tannins and anthocyanins). Rich sources in antioxidants have been considered important for the maintenance and promotion of health. The aim of this work was to quantify the antioxidants compounds and determine the total antioxidant activity of cashew apple pulp. The Cashew apples (BRS 226 clone) were obtained at the Pacajus experimental station from Embrapa Tropical Agroindustry, Ceará, Brazil. The cashew apple pulp was utilized to measure the concentration of total polyphenols by Folin-Ciocalteau method, vitamin C (Strohecker e Henning, 1967), total carotenoids (Higby, 1962), anthocyanins and yellow flavonoids (Francis, 1982) and total antioxidant activity by the ABTS and DPPH methods. The values were, respectively, 626.5 ± 3.536 mg/100g of pulp, 115,62 ± 2,058 mg/100g of pulp, 0.71 ± 0.0036 mg/100g of pulp, 3.40 ± 0.6777 mg/100 g of pulp, 10.19 ± 1.3046 mg/100 g of pulp, 14.495 ± 0.2475 µM Trolox/g of pulp and 6131.909 ± 46.444 g of pulp /g DPPH. The cashew apple pulp phytochemical profile revealed a significant presence of antioxidant compounds as well as a good total antioxidant activity.
