  author={N. Cachet and E. Regalado and G. Genta-Jouve and M. Mehiri and P. Amade and O. Thomas},
The chemical composition of the Caribbean sponge Pandaros acanthifolium was investigated and led to the isolation of seven new steroidal glycosides namely pandarosides A-D (1, 3, 4 and 6) along with the three methyl esters of pandarosides A, C, and D (2, 5 and 7). Their structures were characterized as 3beta-[beta-glucopyranosyl-(1-->2)-beta-glucopyranosyloxyuronic acid]-16-hydroxy-5alpha,14beta-poriferast-16-ene-15,23-dione (1) and its methyl ester (2), 3beta-[beta-glucopyranosyloxyuronic acid… Expand
