Abstract

Background & Aims: Sea urchin immune responses are directly exposed to potentially pathogenic microorganisms and develop defence responses mainly based on immunocytes and humoral factors contained in the coelomic fluid. In addition, the polyhydroxylated 1, 4-naphthoquinone pigments are found to possess excellent antimicrobial, antialgal and antioxidant activities. The present research aimed to study the bioactive potentials (antioxidant, antibacterial and cytotoxic) of coelomic fluid and pigments shells and spines of sea urchin, Echinodermata mathaei species. Methods: The coelomic fluid and pigments shell and spine of sea urchin were isolated using buffered mode and hydrogen chloride (HCl), respectively. Then, antioxidant [reducing power, DPPH radical (1, 1-diphenyl 2-picryhydrazyl) scavenging, and total antioxidant capacity), antibacterial (minimum inhibitory concentration or MIC) and cytotoxic potentials were evaluated. Results: The free cells of the coelomic fluid had the highest activity in the all antioxidant methods, and the coelomocyte lysate had the highest antibacterial activity. All the differences were significant at the level of P < 0.05. Conclusion: The result of this research indicated that coelomic fluid and pigments shell and spine of sea urchin, Echinodermata mathaei species, have potent antioxidant activity and the ability for scavenging cytotoxic effects. This suggests that sea urchin shells and spines, most of which are discarded as waste after removal of gonads, would be a new bioresource for natural antioxidants.
