A novel marine steroidal sulfate from the starfish luidia ludwigi
A new steroid, 5α-cholestane-3β,5,6β,15α,26-pentol 26-sulfate [3], has been isolated from the starfish Luidia ludwigi. This compound co-occurs with two known asterosaponins, acanthaglycosides B and C, and two polyhydroxysteroids [1 and 2], isolated previously from the starfish Myxoderma platyacanthu...
