Abstract

In the present investigation the chemical composition and bioactive compounds of grains of 30 accessions of kiwicha (Amaranthus caudatus L) were evaluated. The total dietary fiber (TDF) was found between 7.50 to 14.12 %, the total phenolic compounds between 51.34 to 75.69 mg GAE/100 g sample, total flavonoids between 12.65 and 36.58 mg CE/100 g of sample. The amylose evaluations using NaOH and DMSO as dispersants showed significant correlation between the results (r2 = 0.883). Statistical differences were found for all the bioactive compounds and antioxidant capacity in all the kiwichas evaluated. Statistical analysis of correlation of total phenolic compounds with antioxidant capacity according to the radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) showed significant correlation coefficients 0.610 and 0.714 respectively. The correlation coefficient between the antioxidant capacity with the DPPH and ABTS radical was 0.823.
