Phytochemical examination of the methanolic extract of fruit bodies of the Xylariaceous ascomycete fungus Hypoxylon fuscum led to the isolation of two azaphilone derivatives named daldinins E and F together with two known compounds daldinin C and 4,5,4′,5′-tetrahydroxy-1:1′-binaphthyl using a combination of reversed phase HPLC and high performance gel permeation chromatography. Their structures were...
Three squalene-type triterpenoids named concentricols B, C and D (1–3) were isolated from the ethyl acetate extract of fruiting bodies of the xylariaceous ascomycete Daldinia concentrica. Their absolute structures were elucidated by analysis of 2D NMR, MS, IR and UV spectra, and the modified Mosher's method.
