The necessary of the thesis Vietnam is endowed with more than 1 million km2 of sea area tropical monsoon climate densely estuarine which are ideal conditions for a diverse and rich marine organison. Since the 1970s there have been a few studies on natural compounds from marine organison. However comparing to the potential source of marine life in our country up to now the research in this field is still too few and scattered especially the studies in echinoderms. Starfish are invertebrates belonging to echinoderms and have long been known as a nutritious source. About 1800 species of starfish occur in all the world s oceans from tropics to frigid polar water. However only about 80 species have been studied for their chemical composition and biological activity. The Oreasterdae family includes 20 genera Acheronaster Anthaster Anthenea Astrosarkus Bothriaster Choriaster Culcita Goniodiscaster . Currently there are only 9 species of the Oreasterdae family which were studied in the world of which 2 species have .
