Two new benzofuran derivatives [I], mp 235-237°, C_<15>H_<10>O_5 and [II], mp 179-181°, C_<16>H_<12>O_5,together with l-maackiain, stigmasterol, medicagol, formononetin and 2', 4', 4-trihydroxychalone (isoliquirtigenin) were isolated from the aerial parts of Sophora tomentosa L., and the structures of I and II were established to be 2-(2', 4'-dihydroxyphenyl)-5,6-methylenedioxybenzofuran and 2-(2'-hydroxy-4'-methoxyphenyl)-5,6-methylenedioxybenzofuran on the bases of chemical and spectral evidence, respectively.
