Three kinds of phenolic biscoclaurine-type bases are obtained from the embryo (lien tze hsin) of lotus (Nelumbo nucifera GAERTN.), liensinine (I), isoliensinine (II), and neferine (III). By utilizing their O-trideuteromethylation and the deuterium-exchange reaction of the aromatic proton, the signals for the methoxyl group and the aromatic proton in the NMR spectrum of O, O-dimethylliensinine (IV) were assigned as shown in Chart 1.
