Abstract: | The aim of the study was to confirm the presence of rutin, one of the most common quercetin glycosides, and other quercetin
derivatives in plants of genus Amaranthus, to investigate the influence of the species and variety on rutin distribution in the plant and content changes during growing
season. The rutin content was determined by micellar electrokinetic capillary chromatography in individual plant parts at
the beginning of the growth, at the flowering stage and at the maturity stage of five Amaranthus species. The total quercetin content was determined by micellar electrokinetic capillary chromatography too. The rutin content
in amaranth ranged from 0.08 (in seeds) to 24.5 g/kg dry matter (in leaves). Comparison of the determined total quercetin
content and the calculated content of quercetin released from rutin did not prove important presence of quercetin or other
quercetin derivatives than rutin. Only amaranth leaves sampled at the maturity stage probably contained quercetin or quercetin
derivatives. Significant differences in the rutin content were established among species and as well varieties. Amaranthus hybrid and A. cruentus were the best sources of rutin. |
