“…Cambios en los contenidos y composición de compuestos fenólicos de las plantas generan variaciones en sus propiedades organolépticas y funcionales (Scarano et al 2018), por lo que el registro exacto de esos cambios puede ser útil en el control de calidad de plantas alimenticias y medicinales. Los resultados de los análisis de agrupamiento indican que los contenidos de compuestos fenólicos y las capacidades antioxidantes de las semillas de frijol común pueden ser útiles como quimiomarcadores para el desarrollo de herramientas de control de calidad, como se ha sugerido para Physalis angulata (Cobaleda-Velasco et al 2017) y Physalis ixocarpa (Hernández-Pacheco et al 2022).…”

In the present study, the variation in the contents of total phenolics, flavonoids, condensed tannins, and iron reducing power of fivewild populations of common bean (Phaseolusvulgaris L.) from the state of Durango, Mexico, was determined every two months,during six months of storage. For comparative purposes, the Negro Bola variety was analyzed in the same manner. The resultsrevealed a decrease in the phenolic compounds levels and in the reducing power for all the samples analyzed, but with importantvariations in the percentages of decrease between samples. The variations found suggest the existence of a high genetic diversityamong the wild forms. The results of the cluster analysis suggest that the variations in the levels of the different phenoliccompounds and in the reducing power were of such a magnitude that they allowed to discriminate between the seeds of differentgenotype at any time of storage, thus they can be useful chemomarkers for the development of quality control tools for commonbean.Keywords: Common bean, seed aging, phenolic content.AÑO 10 NÚMERO 19132 -140CambiosdeloscontenidosdecompuestosfenólicosycapacidadantioxidanteduranteelenvejecimientodesemillasdepoblacionessilvestresdePhaseolusvulgaris(fabaceae)Changes in the contents of phenolic compounds and antioxidant capacity during the aging of seeds of wildpopulations of Phaseolusvulgaris(Fabaceae).
