Two new glycosides from the soft coral Sinularia firma.
Two new glycosides, named Firmacosides A and B, together with known fatty esters, batyl alcohol, Delta(5,20) sterol and sphingosine derivatives have been isolated from the soft coral Sinularia firma TIX-DUR. On the basis of spectroscopic analysis ((1)H-NMR, (13)C-NMR, (1)H-(1)H COSY, HMQC, HMBC and FAB-MS), Firmacoside A was established as hexadecanyl-1-O-alpha-D-arabinopyranosyloxy (1-->4)-alpha-D-arabinopyranosyloxy (1-->4)-alpha-D-arabinopyranoside (1), and firmacoside B was elucidated as docosanyl-1-O-alpha-D-arabinopyranosyloxy (1-->4)-3-O-acetyl-alpha-arabinopyranosyloxy (1-->4)-alpha-D-arabinopyranoside (2).
