Domesticine methyl ether, which had been known to exist only in the fruit of Nandina domestica, has been found from the trunk bark and the roots. Nandinine, whose existence had been questionable, was not found by the authors. Moreover, it was found that domesticine does not show a constant melting point of 116-117° but gives different melting points under various recrystallization, solvents and other conditions. These melting points were: m.p. 115-116° when recrystallized from water and methanol, m.p. 84-85° when recrystallized from absolute methanol or benzene, and m.p. 152-153° (decomp.) when dried at 60° over phosphorus pentoxide in vacuum. By the reduction of the quarternary base, tetrahydroberberine and tetrahydrojatrorrhizine were proved. In other words, roots and trunk bark of Nandina domestica was found to contain jatrorrhizine, as well as the hitherto-known berberine, as the quarternary base. It was also found that Nandina domestica did not contain biscoclaurine type base.
