Summary:A new isoflavone glycoside named as 8-O-methylrelusin-7-O-β-D-apifuranosyl-(1→2)-β-D-glucopyranoside (1), together with two known compounds, 8-O-methylrelusin-7-O-β-D-glucopyranoside (2) and isobiflorin (3), were isolated from Abrus cantoniensis. The structure of the new compound was elucidated on the basis of spectroscopic methods including extensive 1D NMR, 2D NMR, and HRESIMS. This is the first report of isoflavone from Abrus cantoniensis. Moreover, all isolated compounds were evaluated for their cytotoxicity against SMMC-7721 and MHCC97-H cell lines.
