摘　　要：Three new biphenyls, 4,7,8-trimethoxy-2,3-methylenedioxydibenzofuran （1）, 7-hydroxy-4,8- dimethoxy-2,3-methylenedioxydibenzofuran （2）, and 3＇,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 I and compound 2 showed mild α-glucosidase inhibitory activity.Three new biphenyls, 4,7,8-trimethoxy-2,3-methylenedioxydibenzofuran （1）, 7-hydroxy-4,8- dimethoxy-2,3-methylenedioxydibenzofuran （2）, and 3＇,5-dimethoxy-3,4-methylenedioxybiphenyl （3）, along with eighteen known compounds （4-21） were isolated from the aerial part of Ribes takare D.
