In the previous paper, it was reported that two crystalline compounds, tentatively named B_1 and C_1,were isolated from Sophora subprostrata in poor yield. In the present wark, two new crystalline compounds were obtained from the roots of Sophora japonica in good yields and named B_2 and C_2,respectively. The chemical structures of these four compounds were established as follows : B_1 : l-Maackiain-mono-β-D-glucoside, C_1 : l-pterocarpin, B_2 : d-maackiain-mono-β-D-glucoside and C_2 : dl-maackiain. B_1 seems to be identical with trifolirhizin which was recently reported by J.B. Son Bredenberg et al. B_2 is one of the diastereomers of trifolirhizin and so the name sophojaponicin was proposed.
