Abstract :Seseli gummiferum Pall. ex Sm. subsp. corymbosum insert ignore into journalissuearticles values(Boiss. & Heldr.); P.H. Davis insert ignore into journalissuearticles values(Syn: S. corymbosum Boiss. & Heldr.); insert ignore into journalissuearticles values(Umbelliferae); collected in southern Anatolia was investigated for the presence of coumarins. A new angular-type pyranocoumarin, corymbocoumarin insert ignore into journalissuearticles values(1);, along with 5 known coumarins insert ignore into journalissuearticles values(2-6); were isolated from the aerial parts of this plant. Corymbocoumarin insert ignore into journalissuearticles values(1); was established to be insert ignore into journalissuearticles values(-);-insert ignore into journalissuearticles values(3`S,4`S);-3` -acetoxy-4`-isovaleryloxy-3`,4` -dihydroseselin insert ignore into journalissuearticles values(1); and coumarins 2-6 were identified as insert ignore into journalissuearticles values(-);-insert ignore into journalissuearticles values(3`S,4`S); -3`-acetoxy-4` -angeloyloxy-3` ,4` -dihydroseselin insert ignore into journalissuearticles values(2);, insert ignore into journalissuearticles values(+);-insert ignore into journalissuearticles values(3` S,4` S);-3` -hydroxy-4` -angeloyloxy-3`, 4` -dihydroseselin insert ignore into journalissuearticles values(d-laserpitin); insert ignore into journalissuearticles values(3);, insert ignore into journalissuearticles values(-);-insert ignore into journalissuearticles values(3` S,4` S);-3` -angeloyloxy-4` -hydroxy-3`, 4` -dihydroseselin insert ignore into journalissuearticles values(4);, 3` -acetoxy-4` -isobutyloxy-3`, 4` -dihydroseselin insert ignore into journalissuearticles values(5); and osthole insert ignore into journalissuearticles values(6);, respectively, by spectroscopic methods. The structural elucidation and absolute configurations were determined by chemical correlations with known compounds.
