Beschreibung:
This study determined nutritional quality, content of antioxidant compounds and antioxidantactivity in the rind (mesocarp) of the fruit of 15 genotypes of xoconostle to identify those thathave greater nutraceutical potential. A proximal analysis was conducted. Contents ofbetalain, total phenolic compounds, flavonoids, ascorbic acid and antioxidant activity werequantified. The data obtained were analyzed with an analysis of variance (ANOVA), theTukey test (P ? 0.05) and the Pearson coefficient of correlation. Significant differences in theproximal composition and antioxidant compounds were found among the 15 genotypes. Thegenotype Cambray had the highest total content of betalains (35.06 mg 100 g-1 f.w.). Theantioxidant activity observed in the other genotypes may be due to a synergetic effect of thepresence of total betalains, phenolic compounds, flavonoids and vitamin C. The wildgenotype Chaveñito (O. sainaltense), which had the highest percentage (95.88 %) ofinhibition of the DPPH radical (indicating greater antioxidant activity), can be considered thegenotype with the best nutraceutic quality.
