Concentriols B, C and D, three squalene-type triterpenoids from the ascomycete Daldinia concentrica.
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.
