Abstract excerpt
Folin-Ciocalteu and TEAC (Trolox equivalent antioxidant capacity) assay together with the spectrophotometric determination of betalains were applied to investigate the correlation between phenolics and their contribution to the antioxidant capacity of five different Costa Rican genotypes of purple pitaya (Hylocereus sp.) and of H. polyrhizus fruits. Maximum antioxidant capacity, total phenolic and betalain...
