QUANTITATIVE ESTIMATION OF FLAVONOIDS IN VIGNA UNGUICULATA, DOLICHOS BIFLORUS, LENS CULINARIS AND PHASALEOUS VULGARIS SEEDS BY USING UV SPECTROSCOPY

Abstract

Flavonoids are a group of plant metabolites to provide health benefits through cell signalling pathways and antioxidant effects. Flavonoids are abundant in plants, in which they perform several functions. They are essential pigments for producing the colors needed to attract pollinating insects. In higher order plants, flavonoids are also required for UV filtration, nitrogen fixation, cell cycle inhibition, and as chemical messengers. In the present study the quantitative estimation of flavonoids has been done on ethanol extracts of seeds of Vigna unguiculata, Dolichos biflorus Lens culinaris and Phasaleous vulgaris belonging to family Leguminosae. It is found in the study that flavonoids are present in all four plant seeds. Flavonoids are important antioxidants, and promote several health effects. Aside from antioxidant activity, these molecules provide the beneficial activity like anti-viral, anti-cancer, anti-inflammatory, anti-allergic.
