An investigation of basic component from Michelia Champaca LINN (Japanese name “Kin-Koboku”) gave ushinsunine (I) and oxoushinsunine (liriodenine) (II) as a tertiary non-phenolic base, as well as magnoflorine (III) and unknown base, m. p. 260°(decomp.) as a water-soluble quaternary base, which were isolated to picrate, respectively. Both ushinsunine (I) and oxoushinsunine (II) were found to distribute populary, especially in Michelia genus.
