摘要
Four new bisabolane sesquiterpenoids daedatrins A-D(1-4),a cadinane sesquiterpene 12-hydroxy-α-cadinol(5),and a heptanorergosterane derivative daedatrin G(6)were isolated from cultures of the basidiomycete Daedaleopsis tricolor.Their structures were elucidated by spectroscopic methods including extensive 2D NMR techniques and X-ray crystallography.All the compounds showed no significant activity against five human cancer cell lines.
