Domestic Fagara genus plants contain Fagara ailanthoides Engl. and Fagara schinifolia Engl. The former yielded yellow needle crystals of m.p. 146-147°, corresponding to C13H10O5, and this was proved to be isopimpinellin. The latter yielded yellowish white needle crystals of m.p. 188°, corresponding to C12H8O3, and of m.p. 121°, corresponding to C7H6O2, which were respectively proved as bergapten and benzoic acid.
