Chemical constituents from cultures of the basidiomycete Trichaptum pargamenum

Four cadinane-type sesquiterpenes (1-4) and four 13-carbon γ-lactones (5-8), together with three known compounds, were isolated from cultures of the basidiomycete Trichaptum pargamenum. Their structures were elucidated on the basis of extensive spectroscopic methods. The absolute configurations of 1 and 3 were confirmed by single crystal X-ray diffractions.
