title: A new isoflavone from Genista corsica.
abstract: A new isoflavone (1), dihydroisoderrondiol [(3' 'S,4' 'R)-5,7,3' ', 4' '-tetrahydroxy-2' ',2' '-dimethyl-3' ',4' '-dihydropyrano(5' ',6' ';3' ',4' ')isoflavone], was isolated from aerial parts of Genista corsica, together with 11 previously known compounds [daidzein, isoprunetin, isoderrone (2), ficuisoflavone (3), luteolin, luteolin 4'-O-beta-glucoside, luteolin 7-O-beta-glucoside, taxifolin, 5-methoxytaxifolin, sucrose, and D-pinitol]. The structure of 1 was elucidated by spectroscopic methods.
