A qualitative and quantitative analysis of flavonoids has been carried out for first time inVicia eristalioidesMaxt. and inVicia kalakhensisKhatt., Maxt. Bisby. Free aglycones were consistently absent from both species while kaempferol derivatives were pre dominant inV. kalakhensis;a more complex mixture of flavonoid glycosides,(kaempferoland quercetin glycosides) was present inV. eristalioides. Therer was no evidence of flavones glycosides.The flavonoid patterns ofV. kalakhensisandV. eristalioideswere compared with that ofV. narbonensiswhich is considered to be the ancestor of the Narbonensis complex. The results indicate that qualitative and quantitative flavonoid data may be used in the study of the organization and evolution of the Narbonensis complex.
