Estudo morfológico comparativo das cascas e folhas de Stryphnodendron adstringens, S. polyphyllum e S. obovatum - Leguminosae

Abstract

Stryphnodendron (S.) é um gênero da família Leguminosae, subfamília Mimosoideae, tipicamente de clima tropical e subtropical sul americano. Extratos das cascas são utilizadas pela população para diversas doenças, como leucorréias e diarréias, antiinflamatório, anti-séptico (antimicrobiano), promovendo a coagulação sangüínea, em casos de feridas como cicatrizantes, e em alguns casos de ulcerações gástricas. A revisão de literatura mostrou apenas estudos de morfoanatomia da espécie S. adstringens (Mart.) Coville. Assim, esse artigo propôs uma comparação morfoanatômica das cascas e morfológica das folhas de três espécies de barbatimão [S. adstringens, S. polyphyllum e S. obovatum], visando contribuir na identificação botânica e ao controle de qualidade. Para a análise microscópica das cascas, realizaram-se cortes de material emblocado em parafina. As análises macroscópicas e microscópicas das cascas não mostraram diferenças suficientes que possibilitem a diferenciação entre as espécies. As análises macroscópicas das folhas mostraram diferenças morfológicas quanto ao tamanho, coloração e pubescência. Assim, as folhas de S. adstringens possuem maior tamanho, glabras e concolores. Já as folhas de S. polyphyllum são menores, pubescentes e discolores, enquanto que as folhas de S. obovatum são de tamanhos semelhantes ao S. polyphyllum, porém glabras e discolores.

The genus Stryphnodendron (S.) belongs to the family Leguminosae, subfamily Mimosoideae, which includes mostly trees of tropical and subtropical South America. Extracts of the stem bark are used traditionally by the local population to treat leucorrhoea and diarrhoea, as anti-inflammatory and antiseptic agents (antimicrobial) and to promote blood clotting and wound healing, and in a few cases of gastric ulcers. A review of the literature presented a previous morpho-anatomical study only for S. adstringens (Mart.) Coville. The aim of the present work is to compare morpho-anatomically the stem bark and leaves of three species of Stryphnodendron, known popularly as barbatimão: S. adstringens, S. polyphyllum and S. obovatum, in order to help botanical identification and contribute to quality control. Macro- and microscopical evaluation of the stem barks revealed no significant differences among the species. Morphological analyses of the leaves revealed differences in size, coloration, and pubescence. The leaves of S. adstringens are the largest, glabrous, and concolor. The leaves of S. polyphyllum are smaller, pubescent, and discolor; whereas the leaves of S. obovatum are the same size as those of S. polyphyllum, however, they are glabrous, and discolor.
