ABSTRACT

Flavonoids are low molecular weight natural products. Flavonoids absorb the harmful ultraviolet radiation. They are found in fruits, vegetables, nuts, seeds, stems and flowers further as tea, wine propolis. Flavonoids are a very large group of polyphenolic natural products. The fundamental structural feature of flavonoid compounds is the presence of 2-phenyl-benzo[α]pyrane or flavone nucleus. Flavonoids are known to be very powerful antioxidant; they prevent the degradation caused to body cells by the free radicals and thus positive for our health. Flavonoids determination is done by using Aluminum chloride colorimetric method. The major flavonoids component quercetin is helpful in some of the allergies like hay fever, hives, etc. It inhibits the production and release of histamine and different allergic/inflammatory substances possibly by stabilizing cell membranes of mast cells. To date, more than 6000 different flavonoids have been identified and the number continues to increase. The recently increase in consumer awareness on the health benefits of dietary phytochemicals accompanied by the rapid progress in the field of molecular biology has provided the means and incentive to enhance the functional value of plant material.
