Summary On the basis of comparative chemical and spectral data, the structure of the major saponin, luzonicoside, from the starfishEchinaster luzonicus has been elucidated as2. This is a further example of a novel class of steroidal cyclic glycoside from starfish of the genusEchinaster. Its structure includes a Δ7, 3β,6β-dioxygenated-23-oxosteroidal moiety, already found in the saponins ofEchinaster sepositus, and a trisaccharide moiety, β-D-galactopyranosyl-(1→2) α-L-arabinopyranosyl-(1→2)-β-D-glucuronopyranosyl, bridging C-3 and C-6 of the steroid.
