A new meroditerpenoid from Mayodendron igeum.
A new meroditerpenoid, igeumone (1), together with 18 known compounds (2-19), were isolated from ethanolic extract of the bark of Mayodendron igeum. Their structures were determined by analysis of spectral data or comparison with authentic samples. X-ray crystallographic analysis was employed to unambiguously determine the structure of 1.
