Flavonoids from Erythrina vogelii (Fabaceae) of Cameroon.
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.
