摘要：

Four new 24-O-biosides of 5 alpha-cholestane-3 beta,6 alpha,8,15 beta,24-pentaol, designated as mediasterosides M-1 (1), M-2 (2), M-3 (3), and M-4 (4), and the previously known 5 alpha-cholestane-3 beta,6 beta,8,15 alpha,16 beta,26-hexaol (5) have been isolated from the deep-water starfish Mediaster murrayi. Glycosides 1-3 contain rare carbohydrate moieties with (1-->5) bonds between the monosaccharide units. Compounds 1 and 2 showed the inhibition of cell division of fertilized sea urchin eggs and exhibited moderate hemolytic activities.
