Abstract
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.
