Summary

The trunk wood of Aniba kappleri Mez (family Lauraceae) contains besides sitosterol, octacosanoic acid and rhamnocitrin (7-O-methylkaempferol), three esters, namely benzyl benzoate, benzyl 2-hydroxybenzoate and benzyl 2,6-dihydroxybenzoate, and two α-pyrones, namely 4-methoxy-6- (E) -(3',4'-methy!enedioxystyryl)-2-pyrone and 4-methoxy-6-{E)-(3',4'-dimethoxystyryl]-2pyrone. A dimer of the latter compound, which was obtained additionally, is considered to be an artifact.
