Flavonoids analysis of four Vicia species of Narbonensis complex in two different vegetative phases

A qualitative analysis of flavonoids has been carried out for Vicia eristalioides Maxt., V. kalakhensis Khatt., Maxt. and Bisby, V. narbonensis L. and V. galilaea Plitm. et Zoh in two different vegetative phases. Free aglycones were consistently absent and there was no evidence of flavone glycosides, whereas kaempferol and quercetin glycosides were present in different amounts, according to the species. The flavonoid patterns of the four species were compared and differences were present among them and also within the same species during the two vegetative phases. The results indicate that flavonoid data may be used in the study of the organisation and evolution in Narbonensis complex
