A new ceramide 1 and a known steroidal glycoside 2 were isolated from the sponge Raphiedotethya sp.collected from Sanya bay,Hainan island,China.On the basis of spectroscopic and chemical analyses,their structures were determined as (2S,3S,4R,2'R)-N-(2'-hydroxydocosanosyl)-2-amino-1,3,4-trihydroxy-henicosane (1) and 4-O-[β-D-xylopyranosyloxy]-pregn-20-en-3β,4α-diol (2).
