A new 2-arylbenzofuran, named sophorafuran A (I), mp 145-146℃, C_<16>H_<12>O_6,and a new coumestan, named sophoracoumestan B (II), mp over 300℃, C_<17>H_<10>O_7,together with (-)-3-hydroxy-4-methoxy-8,9-methylenedioxypterocarpan (III) were isolated from the root of Sophora franchetiana DUNN (Leguminosae). The structures of I and II were established to be 2-(2', 4'-dihydroxy-3'-methoxyphenyl)-5,6-methylenedioxybenzofuran and 3-hydroxy-4-methoxy-8,9-methylenedioxycoumestan, respectively, on the basis of chemical and spectral evidence.
