Contribuição ao estudo farmacognóstico da mutamba (Guazuma ulmifolia - Sterculiaceae)

Abstract

Guazuma ulmifolia Lam., Sterculiaceae, conhecida popularmente como mutamba, possui ampla distribuição geográfica, existindo desde o México até o sul do Brasil. O interesse pelas suas propriedades químicas deveu-se principalmente pela sua aplicação no tratamento capilar. Esta propriedade pode ser atribuída aos taninos, os quais apresentam atividade farmacológica, antiinflamatória, antiulcerogênica, antimicrobiana, ação de proteção capilar e prevenção na formação de radicais livres. Na análise microscópica das cascas e das folhas foram detectados: grandes canais secretores entre as células do parênquima e tricomas tectores estrelados sobre a epiderme, respectivamente. Um dos objetivos do estudo anatômico das cascas de G. ulmifolia foi detectar tecidos em que havia acúmulo de polifenóis. Como resultado, dois tecidos mostraram-se ricos em idioblastos contendo esta substância: a região floemática e a periderme. A análise química preliminar realizada com as cascas da mutamba mostrou positividade para os grupos químicos flavonóides, taninos, saponinas e mucilagens.

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.
