This study determined nutritional quality, content of antioxidant compounds and antioxidant activity in the rind (mesocarp) of the fruit of 15 genotypes of xoconostle to identify those that have greater nutraceutical potential. A proximal analysis was conducted. Contents of betalain, total phenolic compounds, flavonoids, ascorbic acid and antioxidant activity were quantified. The data obtained were analyzed with an analysis of variance (ANOVA), the Tukey test (P <= 0.05) and the Pearson coefficient of correlation. Significant differences in the proximal composition and antioxidant compounds were found among the 15 genotypes. The genotype Cambray had the highest total content of betalains (35.06 mg 100 g(-1) f.w.). The antioxidant activity observed in the other genotypes may be due to a synergetic effect of the presence of total betalains, phenolic compounds, flavonoids and vitamin C. The wild genotype Chavenito (O. sainaltense), which had the highest percentage (95.88 %) of inhibition of the DPPH radical (indicating greater antioxidant activity), can be considered the genotype with the best nutraceutic quality.
