Considering the high potential of pitaya fruits for industrial use and its nutritional value, the goal of this study was to evaluate the antioxidant capacity of the bark, pulp and seed of the three pitaya species: Hylocereus undatus, Hylocereus costaricensis and Selenicereus megalanthus through the verification of their influence in a free radical analyzing their behavior and effect in one reactive specie.The fruits of H. undatus, H. costaricensis and S. megalanthus (n = 7 of each species), were processed to obtain a sample of the peels, pulp and seed, separately. We determined antioxidant capacity for seeds, pulp and peels, assessed whether they could scavenger DPPH (2,2-diphenyl-1-picryl-hydrazyl) radical. The DPPH is based on its capture by antioxidants, producing a decrease in absorbance at 515 nm. For our positive control, we used butylated hydroxytoluene (BHT), a known antioxidant, diluted in DPPH solution and incubated at room temperature, and compared the antioxidant capacity in scavenging DPPH radical for the three species, using pitaya?s samples with DPPH solution at room temperature.Our results show that, seeds from H. undatus, H. costaricensis and S. megalanthus significantly decreased DDPH radical formation (p<0.001). Moreover, H. undatus and H. costaricensis seeds were more effective in decreasing DPPH radical formation as compared to S. megalanthus seeds (p<0.05). Pulps from pitaya were also able to decreased DPPH radical generation (p<0.05) but in small capacity than seeds. H. costaricensis pulp decreased DPPH radical greater than H. undatus and S. megalanthus pulps (p<0.01); on the other side, peels from H. undatus and H. costaricensis did not decrease DPPH radical formation, while, peel from S. megalanthus was able in reducing DPPH radical (p<0.01). We next compared the antioxidant capacity in scavenging DPPH radical for the sample of three species. Again, the greater antioxidant capacity in scavenging DPPH radical was ascribed for seeds (p<0.001).This work showed that seeds have greater antioxidant activity as compared to pulp and peel. And between species, seeds from H. undatus, and H. costaricensis, showed greater capacity antioxidant than S. megalanthus, which showed better results for the antioxidant capacity of the peel.
