Abstract
Two new drimane sesquiterpenoids, 11,12-dihydroxy-15-drimeneoic acid (1) and 3α,11,15-trihydroxydrimene (2), were isolated from cultures of the basidiomycete Agaricus arvensis, together with one known compound 3β,11,12-trihydroxydrimene (3). Their structures were established by means of spectroscopic analysis.
