Leaves of Bauhinia forficata Link (Fabaceae) are used in the folk medicine for the treatment of diabetes. Considering that the hypoglicemiant activity has been attributed to flavonoids and phenolic compounds, the aim of this work was to detect the presence of them in the first stages of development of this plant, which could reduce the time of collecting and optimize its production. Leaves of six year old plants, grown from seeds, were dried and powdered for extraction of tannins and flavonoids. Tanin were quantified by radial diffusion assay and flavonoids were analysed by conventional chromatography methods and UV spectrometry. Tannins were not detected and the main flavonoids detected were kaempferol glycosides.
