A new flavone, vogeol, and a new isoflavone, vogliiol, have been isolated from Erythrina vogelii, a Cameroonian medicinal plant, along with seven known constituents (salvigenin, carpachromene, euchrenone b10 scandenone, 5,4′-dihydroxy-8-(3″″-methylbut-2″″-enyl)-2″′-(4″′-hydroxy-4″′-methylethyl)-furano-[4″′,5″′:6,7] isoflavone, erythrivarone C, and 5,7,4′-trihydroxy-6-[3″″-methylbut-3″″-enyl]-flavone). Their structures were elucidated by spectroscopic methods.
