Anthocleista djalonensis has provided a new monoterpene diol, djalonenol, as well as the known iridoid glucoside djalonenoside (also sweroside). Also isolated for the first time from a plant source is a dibenzo-alpha-pyrone-djalonensone, previously identified as a fungal metabolite. The structure of the new compound was elucidated on the basis of its chemical and spectral data as tetrahydro-3-hydroxy hydroxymethylene-4-(3-hydroxymethylene prop-1-ene)-2H-pyran-2-one.
