Starfish saponins, Part 50. Steroidal glycosides from the Okinawan starfish Nardoa tuberculata.
This paper describes a complete analysis of the glycoside and polyhydroxysteroid constituents of the starfish Nardoa tuberculata, collected at Zampa, Okinawa, Japan. Besides a group of known non-sulfated steroidal diglycosides, halitylosides A [5], B [6], D [7], E [8], and F [9], and two known polyhydroxysteroids 10 and 11, N. tuberculata also contains four new sulfated steroidal glycosides 1-4 closely related to the previous halitylosides. The antifungal activities and the effects on the development of fertilized sea urchin eggs of some steroid components from this starfish were examined.
