ROLES OF FLAVONOIDS IN PLANTS
Journal Title: International Journal of Pharmaceutical Science and Technology - Year 2011, Vol 6, Issue 1
Abstract
Flavonoids are the low molecular weight polyphenolic secondary metabolic compounds, universally distributed in green plant kingdom, located in cell vacuoles. Flavonoids play a variety of biological activities in plants, animals, and bacteria. In plants, flavonoids have long been known to be synthesized in particular sites and are responsible for color, aroma of flowers, fruit to attract pollinators consequently fruit dispersion; help in seed, spore germination, growth and development of seedling. Flavonoids protect plants from different biotic and abiotic stresses and act as unique UV-filter, function as signal molecules, allelopathic compounds, phytoalexins, detoxifying agents, antimicrobial defensive compounds. Flavonoids have roles against frost hardiness, drought resistance and may play a functional role in plant heat acclimation and freezing tolerance. In the present review, our endeavor is to cover wide range of functions of flavonoids in plant growth, development, propagation and protection against various adverse situations with biosynthetic path way.
