Resumen
Determining the antioxidant activity and the total phenolic content are routine procedures in most
natural product laboratories; however, when dealing with large number of samples, it is necessary
to employ methods that allow a quick, easy and economical screening. The aim of this study is to
determine the antioxidant activity and the total phenolic content of plant species as criteria for the
selection of promising species. To reach this aim, we used twenty species from Yotoco National
Protected Forest in Valle del Cauca, Colombia. The species Clidemia tococoidea and Miconia
aeruginosa, showed the highest total phenolic content together with the best antioxidant activity in
terms of DPPH radical scavenging activity. The excellent correlation (R2=0.9610) shown between
these parameters, demonstrated the utility of the process used as a method for primary screening and
selection of promising species for phytochemical analysis at a preparative scale for this two assays.
