Flavonoids analysis of Vicia species of Narbonensis complex: V. kalakhensis Khatt., Maxt. & Bisby and V. eristalioides Maxt

Abstract A qualitative and quantitative analysis of flavonoids has been carried out for first time in Vicia eristalioides Maxt. and in Vicia kalakhensis Khatt., Maxt. Bisby. Free aglycones were consistently absent from both species while kaempferol derivatives were pre dominant in V. kalakhensis; a more complex mixture of flavonoid glycosides,(kaempferoland quercetin glycosides) was present in V. eristalioides. Therer was no evidence of flavones glycosides.The flavonoid patterns of V. kalakhensis and V. eristalioides were compared with that of V. narbonensis which 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.
