The occurrence of toxic saponins in starfish has been known since some years ago'. They are cytotoxic, hemolytic, antiviral2 and also induce escape reaction in molluscs3. A number of steroidal aglycones produced by acid hydrolysis of star fish saponins (asterosaponins) have been characterized; all o
