PHARMACOLOGY：Rutin, the glycoside form of quercetin, is a bioflavonoid having aromatic trimeric heterocyclic structure. It is a naturally occurring pigment. It, chemically 3-[[6-o-(6-deoxy-alpha-l-mannopyranosyl)-beta-d-glucopyranosyl]oxy]-2-(3,4-dihydroxyphenyl) -5,7-dihydroxy-4h-1-benzopyran-4-one, is a yellow to greenish crystalline powder melting at 190 c. Rutin is classified as vitamin p which increases the strength of the walls of the blood capillaries and regulates their permeability. Others classified as vitamin p are catechin, citrin, eriodictin, hesperetin, hesperidin, nobiletin, quercetin,sinensetin, and tangeretin. It is not a dietary essential but is known to have an effect on capillary disorders. It may also have a contribution to the total antioxidant activity and detoxifiers. It is also known to have pharmacological action as an anti-inflammatory, antihistaminic and antiviral agent.
