A new prenylated isoflavone and long chain esters from two Erythrina species.
Two new compounds, a long chain ester 1 of p-coumaric acid and a prenylated isoflavone, senegalensin [5], 5,4'-dihydroxy-8-(gamma,gamma-dimethylallyl)-[5"-(hydroxyisopropyl ) (2",3":6.7)] isoflavone, in addition to a known long chain ester 2 of ferulic acid, have been isolated and characterized from the stem bark of the Cameroonian medicinal plant Erythrina senegalensis. Another known compound 3, a long chain ester of ferulic acid, was isolated from Erythrina excelsa. The structures of all the compounds were determined by spectroscopic techniques.
