Guazuma ulmifolia Lam., Sterculiaceae, popularly known as mutamba, has a wide geographical distribution, ranging from Mexico to Southern Brazil. The interest in its chemical properties is due to its popular use for hair loss treatment. This activity can be attributed to tannins that have many pharmacological activities such anti-inflammatory, anti-ulcerogenic, anti-microbial, anti-viral, capillary protective action and radical scavenging properties. In the microscopic analysis of barks and leaves, large secretor ducts could be detected among the parenchyma cells, as well as star shaped trichoms on the epidermis. One of the aims of the anatomical study was to detect tissues with polyphenolic compounds. The results indicated two tissues rich in these compounds: the phloematic region and the periderm. Chemical analyses were carried out on the bark and showed the presence of the following chemical groups: flavonoids, tannins, saponins and mucilages.
