【 摘 要 】

Hyptidendron canum(Pohl ex Benth.) Harley, Lamiaceae, is popularly used as an antimalarial, anti-inflammatory, antiulcerative, antihepatotoxic and anticancer agent. The goal of this research was to perform the morphoanatomy study of H. canumleaves and stem and identify the main classes of secondary metabolites present in the of H. canumleaves. Such data have not been reported in the literature. The young leaves and stems were collected in Goiânia (GO), hand sectioned and prepared for microscope analysis. Reactions were performed for the identification of secondary metabolites of the dried and pulverized material. The crude ethanol extract was prepared and then fractioned by liquid-liquid partition with hexane, chloroform and ethyl acetate. Thin layer chromatography (TLC) analysis was performed on the fractions. The leaf blades presented adaxial epidermis constituted of polygonal cells with straight walls. On the abaxial epidermis cells with straight to wavy walls and diacytic and anisocytic stomates were noted. Non-glandular and glandular trichomes are present on both faces of the leaf blade. The petiole is grooved, and it presents single layered adaxial and abaxial epidermis. The cross section of the stem presents a generally quadrangular contour with the presence of non-glandular and glandular trichomes. The leaf reactions and TLC evidenced the presence of flavonoids, saponins, terpenes and lignanes. This works helps to increase knowledge of the morphoanatomy and the chemical classes present in H. canum.
