In continuation of the previous work, bases contained in Xanthoxylum planispium SIEB. et ZUCC. (Rutaceae) (Japanese name “Fuyuzansho”) were examined and γ-fagarine (III) was newly isolated from its root. Terrestrial portion yielded manoflorine (IV) and xanthoplanine (XPQR-base I), The kind and content ratio of the bases contained in the root and terrestrial portion are listed in Table I.The new quaternary base, xanthoplanine, is an aporphine-type phenolic base represented by the empirical formula C16H10(OCH3)3(OH)(=N+(CH3)2). Examinations were also made on the reineckate and phenol methods for separation of water-soluble quaternary base and it was proved that the reineckate method is better in easily affording a base of high purity.
