The isolation and structure elucidation of some derivatives of dimethylallyl-coumarin, chromone, quinoline, and phenol from Fagara species, and from Cedrelopsis grevei

Abstract

Extraction of the heartwood of Fagara leprieurii has given 6,7,8-trimethoxycoumarin and skimmianie; Fagara zanthoxyloides gave a new phenol, zanthoxylol, identified as 3-dimethylallyl-4-hydroxyphenylpropanol and 3-dimethylallyl-4-methoxy-2-quinolone. Only sitosterol was obtained from Fagara lemairei. Cedrelopsis grevei gave the known chromone ptaeroxylin and 8-dimethylallyl-7-hydroxy-6-methoxycoumarin.
