As a result of the investigation of alkaloids in the Japanese Mahonia Fortunei Fedde, the authors identified oxyacanthine, berbamine, jatrorrhizine, berberine and palmatine, and confirmed that it furnishes almost the same alkaloids as the Indian Mahonia. It has also been clarified that the Japanese Mahonia japonica DC. contains isotetrandrine and berbamine as the tertiary bases, whereas Mahonia Fortunei Fedde furnishes oxyacanthine and berbamine. Furthermore, it has been found that in Mahonia japonica DC. the root contains quite the same alkaloids as the trunk.
