In the last five years only a few examples of asterosaponins have been published in the literature. These include new pentaglycosides from the starfishes Labidiaster annulatus, Luidia quinaria, Psilaster cassiope and Culcita novaeguineae, together with three new hexaglycosides from the Patagonian starfish Anasterias minuta. Cytotoxie and antifungal activities were reported for some of these saponins as well as structure-activity...
