Three new biphenyls, 4,7,8-trimethoxy-2,3-methylenedioxydibenzofuran(1), 7-hydroxy-4,8-dimethoxy-2,3-methylenedioxydibenzofuran(2), and 30,5-dimethoxy-3,4-methylenedioxybiphenyl(3), along with eighteen known compounds(4–21) were isolated from the aerial part of Ribes takare D. Don. Their structures were elucidated on the basis of spectroscopic data. Compound 1 and compound 2 showed mild a-glucosidase inhibitory activity.
