| dc.description.abstract | This study evaluated the antibacterial and antioxidant potential of brittle stars methanol extract. Three species of brittle star collected along the intertidal zone of Diguisit, Baler, Aurora were identified based on morphological approach using diagnostic keys. The species were identified as follows: Breviturma dentata, Breviturma brevipes and Ophiocoma aethiops. The antibacterial potential was evaluated using the paper disc method and zone of inhibition was measured against E. coli and S. aureus, B. brevipes recorded the highest diameter zone of inhibition against E. coli and S. aureus after 48 hours of incubation with 16.17 ≠0.42mm and 13.85≠5.55mm respectively. O. aethiops only inhibited S. aureus with zone of inhibition of 7.10≠0.18mm in 48 hours and no antibacterial potential against E. coli, while B. dentata did not show inhibitory effect at all. Antioxidant property of brittle stars were evaluated using DPPH radical scavenging assay. O. aethiops got the highest radical scavenging activity with 35.71% among the three species of brittle stars. This was followed by B. dentata and B. brevipes having the same radical scavenging activity of 32.65%. Based on the results, the collected species of brittle stars has antibacterial and antioxidant potential. | |
