A flavonoid glycoside, Rutin (1) a well-known natural antioxidant, is one of the medicinally important flavonoid, which was isolated from the flowering buds of Bauhinia tomentosa(FBBT) as greener manner with excellent yield. Many more studies had been done for the isolation of rutin by different methodology. The necessity of finding a better and/or cheaper commercial source for rutin and other related phenolic compounds is still valid for the utility of the compounds. During this study rutin was isolated from Bauhinia tomentosa by simple methodology, greener manner and excellent yield (6.5%). The structure of the compound was established by means of extensivechemical and spectral evidences.
