New xanthorin glycosides from a Dermocybe species.
A mixture of the 8-O-beta-D-glucopyranoside of omega-hydroxyxanthorin 1-O-methyl ether (3) and the 8-O-beta-D-gentiobioside of xanthorin 1-O-methyl ether (4) was isolated from the water-soluble extractives of the Australian toadstool Dermocybe sp. WAT 22963. Compounds 3 and 4 were identified by characterization of their respective peracetyl derivatives 5 and 6.
