【 摘 要 】

Jacaranda puberula is popularly known as "carobinha" and is used in medical practices of many folk communities. The objective of this work was the anatomical and chemical characterization of Jacaranda puberula (Bignoniaceae) leaves. The anatomical analysis was carried through light microscopy and scanning electron microscopy (SEM). For the chemical analysis it was used High Perfomance Liquid Chromatografy (HPLC). Cross and paradermic sections of leaf showed the presence of uniseriate epidermal cells covered by a thick cuticle layer. There are peltate gland trichomes of multicellular type and no gland trichomes (tectores). It was observed that the faces of mesophyll are distinctly. Two to three layers of palisades cells form chlorophylian parenchyma and lacunary parenchyma is formed of four to five layers of small size cells with many intercellular spaces, pinad ribbing, hipoestomatic. The SEM studies evidenced estomata in the abaxial face of the epidermis covered with epicuticular wax. Eight secretory cells covered by cuticle form the peltate gland trichome. The chromatographic analysis of the ethanol extract evidenced the presence of phytoquinoids and flavonoids.
