Four derivatives of daidzein such as daidzein-7-O-phosphate, daidzein-7-O-beta-D-glucoside, daidzein-7-O-beta-(6 ''-O-succinyl)-D-glucoside, and 4 '-Ethoxy-daidzein-7-O-beta-(6 ''-O-succinyl)-D-glucoside were isolated from the biotransformation reaction mixture. The structures of the molecules were elucidated by HPLC, HR-QTOF-ESI/MS and H-1-NMR analyses. Among them 4 '-Ethoxy-daidzein-7-O-beta-(6 ''-O-succinyl)-D-glucoside derivative is novel compound and not reported elsewhere till now.
