About 600 species of Passiflora are described around the world, of which 120 are native to Brazil. In the present work, the phytochemical compounds were analyzed by high-performance liquid chromatography, and the antioxidant activities (AOX) were measured in the pulp of P. edulis and P. cincinnata species. The P. edulis presented a higher bioactive content and AOX when compared to P. cincinnata. Citric and malic acids were the main organic acids found. The principal component analysis-PCA associated the highest values of quercetin-3-glucoside, hesperidin, trans-caftaric acid, chlorogenic acid, caffeic acid, p-coumaric acid, trans-resveratrol, rutin, procyanidin-B2, epigallocatechin-gallate and epicatechin-gallate, to P. cincinnata. The P. edulis was associated with higher values of total phenolic, vitamin C, total carotenoids, AOX (DPPH center dot, ABTS(+center dot) and FRAP), cis-resveratrol, naringenin, kaempferol-3-glucoside, myricetin and procyanidin-B1. P. cincinnata, although not a commercial species such as P. edulis, presented phenolic compounds and antioxidant activity in acceptable values, including the high values of quercetin 3-glucoside. The present study contributes to the knowledge of the physical-chemical composition of the Passiflora species.
