| dc.description.abstract | This study investigated the antioxidant, antimicrobial and cytotoxic properties of a purified yerba mate polysaccharide. The yerba mate polysaccharide showed a prominent antioxidant activity as evaluated by 2,2-diphenyl-1- picrylhydrazyl (DPPH•)-radical scavenging activity (IC50 = 1.25 ± 0.10 mg/mL), 3-ethyl benzothiazoline-6- sulphonic acid (ABTS•+)-radical scavenging activity (IC50 = 0.41 ± 0.05 mg/mL), and hydroxyl scavenging activity (IC50= 3.36 ± 0.31 mg/mL). The antioxidant activity evaluated as the ferric ion reduction power (FRAP) and oxygen radical absorbance radical assay (ORAC), expressed as trolox equivalents,were 20.84±1.61 μMTE/- mg and 556.30± 12.83 μM TE/mg, respectively. The purified yerbamate polysaccharide presented high antimicrobial activity against several bacterial and fungal strains; however, no cytotoxicity against all four tumor human cell lines assessed. | |
