CHEMICAL CONSTITUENTS FROM THE FRUITING BODIES OF THE BASIDIOMYCETE ALBATRELLUS SP.

A new prenylated orcinol derivative, namely albatrellutin [3'R-(7',11'-dimethylnona-6',10'-dienyl)-3',7-dimethyl-chroman-1-ol] (1), together with eight known compounds was isolated from ethyl acetate extract of the fruiting bodies of the basidiomycete Albatrellus sp. The structure of this new compound was completely elucidated using a combination of 2D NMR techniques (COSY, NOESY, HMQC and HMBC) and HR-EI-MS analyses. The known compounds were elucidated by comparison of their spectroscopic and physical data with those reported in the literatures.
