Abstract

Three novel steroidal monoglycosides, pycnopodiosides A, B, and C (I, II, and III, resp.), together with 1 novel polyhydroxysteroid (IV) were isolated from the starfish P. helianthoides collected off the Gulf of California. These compds. co-occur with the common asterosaponin thornasteroside A, the known steroidal monoglycoside, coscinasteroside B, and 2 known polyhydroxysteroids. The structures of the new metabolites were detd. from spectral data and comparison with those of related steroids.
