Studies on the Alkaloids of Rutaceaous Plants. IV

Examinations were made on the presence of alkaloids in Xanthoxylum ailanthoides SIEB. et ZUCC. (Fagara ailanthoides (SIEB. et ZUCC.) ENGL.) (Japanese name ‘Karasuzansho’) (Rutaceae family, growing wild in the suburbs of Kyoto city, known dictaminine (IV) and skimmianine (V) were isolated as tertiary bases, magnoflorine (II) as the water-soluble quaternary base, and a minute amount of a base (flavianate, m. p. 189° (decomp.)), from the wood. The bark yielded the water-soluble quaternary base, laurifoline (I), but it contained almost no tertiary base.
