Resumen en inglés

The fireworm Hermodice carunculata PALLAS, 1766 belongs to the family amphinomidae, is characterized by its hive bite and the presence of calcified quetas that cover its entire body, however, its aposematic coloration is the most striking of this species. These organisms have varied and bright colors and some can reach large size. With this work, antioxidant activity was evaluated by the methods of the radical DPPH• and ABTS+• of the primary methabolic extract of the species Hermodice carunculata of exposed environment and protected from the swell, collected in dry and rainy season, by means of free search and manually. Antioxidant activity was determined to have no significant results (IC50 > 1000 mg/ml), but IC5O values allowed the study to be brought to comparison of extracts by the possibility of active secondary metabolites. The mean inhibitory concentration (IC50) had variations between the two sectors, so that those in exposed environments were considered "better activity" as they had lower concentration than the rest. On the other hand, these values were influenced by the action of the swell, the values furthest from the activity, were associated with the low impact environments of the waves, therefore, the effect of temperature and precipitation was added to it, also the coloration and size was a fundamental factor to attribute it to the antioxidant activity of Hermodice carunculata. It was proven through an analysis of main components that yellow and large specimens had low activity compared to those of brown and smaller size.
