Chlorophyll, Carotenoid and Flavonoid Contents in Vegetative Organs of Vicia Faba L.

Abstract

Leaf and stem tissues of broad bean (Vicia faba L.) were analyzed for chlorophyll, carotenoid and flavonoid concentrations. Total clorophyll concentration was 6,258 mg/kg in leaves and 570 mg/kg in stems, with a dominance of chlorophyll a 2.2-2.4:1 ratio. Average carotenoid concentration reached 4,317 mg/kg in leaves and 404 mg/kg in stems. Flavonoids had elevated concentrations, with an average of 108,179 mg/kg in leaf tissue and five times lower, 20,423 mg/kg in broad bean stems. These values make broad bean a valuable forage plant.
