Abstract
Marine organisms living in the shallow water ecosystems are potentially exposed to the highest and harmful levels of UV radiation. The starfish Archaster typicus lives in the shallow water habitat and, therefore, is exposed to the highest level of UV radiation, suggesting that this starfish contains UV absorbing compounds to diminish the direct and indirect damaging effects of environmental UV radiation. This study aimed to identify the UV absorbing compounds in the Indonesian starfish A. typicus. Two UV absorbing compounds, palythine (1) and asterina-330 (2), were isolated from A. typicus collected at Tasik Ria, North Sulawesi, Indonesia. The structures of these compounds were assigned on the basis of their spectroscopic data and confirmed by comparing these data with those for the reported values. This is the first report of isolation UV absorbing compounds from A. typicus.
