Cactus pear fruit (Opuntia) are harvested from various species of the genus Opuntia of the cactus family (Cactaceae), and are produced and consumed in several countries. We have characterized the nutritional content and antioxidant capacity (AC) of the fruit of ten cultivars/lines of distinct pulp colors. ‘Camuesa’ had the highest betalains, total carotenoids, ß-carotene, ascorbic acid, and was one of the highest in total phenolic compounds, but its AC did not demonstrate outstanding differences with some other cultivars/lines that were not as rich in these compounds. ‘Roja Pelota’ had high AC when measured with the DPPH assay, but had low total carotenoids, ß-carotene and total phenolic content. ‘Reyna’ had slightly low AC as measured by the FRAP assay, practically no betalains, and low vitamin C, tocopherols, ß-carotene, and total phenolic content.
