Flavonoid Contents From Some Exotic Tree Species Growing In Rajasthan Desert

Evaluation of flavonoid contents from four selected exotic tree species like Colophospermum mopane, Holoptelea integrifolia, Kigelia pinnata and Putranjiva roxburghii growing in Rajasthan Desert was carried out. The leaves of selected trees were analysed for flavonoid contents i.e. Quercetin and Kaempferol. Flavonoid contents like Quercetin and Kaempferol were isolated and identified. The maximum total flavonoid contents (17.10mg./gdw) was found in leaves of Putranjiva roxburghii while minimum (9.20mg./gdw) in leaves of Holoptelea integrifolia.
