Dasyphyllum tomentosum (Spreng.) Cabrera, which belongs to the Asteraceae family, is well known for having many species with therapeutic properties. The aim of this study was to evaluate the extracts and fractions from the leaves and stem bark of D. tomentosum with respect to the antioxidant, cytotoxic and hemolytic activity in in vitro tests. All samples showed antioxidant activity by the DPPH inhibition method, especially the ethyl acetate fraction obtained from the leaves, whose activity was comparable to that of standard ascorbic acid and rutin. Regarding the reduction of the phosphomolybdenum complex, we noted that this same fraction was only similar to rutin and the fraction obtained from the stem bark showed superior results. There was no cytotoxicity and hemolytic activity compared to the models used in the extracts and fractions. The results demonstrate the antioxidant potential of the species without showing toxicity.
