Da casca do tronco de Hymenaea courbaril var. altissima (Ducke) foi isolado um novo entclerodano na forma de éster metílico, após esterificação com diazometano, o (-)-(5R,8S,9S,10R)clerod-3-en-15-oato de metila. Foram isolados também dois ent-labdanos conhecidos: o (-)-copalato de metila e (-)-eperuato de metila. Do extrato AcOEt do epicarpo foi isolado, após esterificação com diazometano, o (-...
