Antioxidant coumarin and pyrone derivatives from the insect-associated fungus .

Two new compounds, versicolones A and B ( and ), and three known pyrone derivatives (-) were isolated from the insect-associated fungus . Their structures were elucidated through a combination of HRESIMS and NMR spectroscopic analysis. Versicolone A () was revealed as a coumarin derivative with the rare 5-alkyl side chain substitution.
