A NEW NEODOLASTANE DITERPENE FROM CULTURES OF THE BASIDIOMYCETE TRAMETES CORRUGATA

摘要

A New diterpene with a neodolastane skeleton, named 2,5-epoxy-5,13-dihydroxyneodolast-3-en-14-one (1), was isolated from cultures of the basidiomycete Trametes corrugate together with guanacastepene E. The structure of 1 was elucidated on the basis of extensive spectroscopic analysis including 1R, MS,1D and 2D NMR experiments.
