El presente estudio tuvo como objetivo determinar las capacidades de captación de radicales libres de T. paradoxa (TP) y B. appendiculata (BA) utilizando el ensayo DPPH, SOD, fosfomolibeno y ABTs. El mejore valor de CI50 en los ensayos de DPPH de para extractos de TP fue el metanólico (102,25 µg / mL) y para los extractos de BA, la acetona (121,06 µg/mL). Entre los diversos extractos probados, los extractos metanólicos de BA y TP mostraron la mayor actividad antioxidante. La capacidad de captación de radicales libres de SOD de los extractos de TP fue CI50= 123,46 µg/ml con éter de petróleo y de los extractos de BA, CI50= 108,7 µg/ml con acetona. La capacidad de eliminación de radicales libres de los extractos de BA y TP fue acetona (CI50 = 76,92 y CI50 = 77,88 µg / ml respectivamente).
The present study was aimed to determine the free radical scavenging abilities of Tectaria paradoxa (TP) and Bolbitis appendiculata (BA) using DPPH, SOD, phosphomolybdenum and ABTs assay. The better DPPH assays IC50 values of TP extracts was the methanolic extract (102.25 µg/mL) and for BA extracts was acetone (121.06 µg/mL). Among the various extracts tested, methanolic extracts of BA and TP displayed highest antioxidant activity. The SOD free radical scavenging ability of TP extracts was petroleum ether IC50= 123.46 µg/mL and for BA extracts was acetone IC50= 108.7 µg/mL. The free radical scavenging ability of BA and TP extracts was acetone (IC50= 76.92 and IC50= 77.88 µg/mL respectively).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
