Flavonoid taxonomic analysis of <i>Vicia</i> species of section <i>Faba</i>

Abstract

The flavonoids rutin, quercitrin, hyperoside, quercetin-3-arabinoside, kaempferol-3-rutinoside, and robinin were identified in leaves of six Vicia species of section Faba. Flavonoid glycosidic pattern was utilized to draw taxonomical relationships amongst the six species. The four botanical varieties of Vicia faba were found to be distinct from the narbonensis group and Vicia bithynica. Indeed, flavonoid fingerprints using high performance liquid chromatography show that the four botanical varieties of V. faba L. are closely related, whereas the wild species separate into three subgroups.
