Resumo(s)
Psychotria viridis Ruíz & Pavón, folha, é um elemento crucial de uma preparação tradicional à base de plantas (PBP), conhecida pelo nome “chá Ayahuasca”. Atualmente essa preparação tem vindo a ser estudada pelos seus diferentes potenciais efeitos terapêuticos, mas na literatura disponível ainda se encontra uma lacuna quanto à diagnose botânica das plantas que fazem parte desta preparação. Por esse motivo neste trabalho procurou-se fazer a diagnose botânica de 15 amostras de Psychotria viridis Ruíz & Pavón, folha., sendo desenvolvida uma análise macroscópica, microscópica através de microscopia ótica e microscopia eletrónica de varrimento, assim como uma análise microscópica quantitativa e histoquímica de forma a possibilitar a identificação e quantificação de elementos úteis para a sua diagnose. Adicionalmente apresentam-se resultados de um estudo efetuado com vista à deteção dos constituintes químicos de PPB contendo possivelmente P. viridis, folha tendo para o efeito sido adaptadas técnicas de extração direcionadas e de caracterização química por Cromatografia em Camada Fina (CCF). Todo o trabalho experimental foi realizado após compilação e pesquisa dos dados bibliográficos de maior relevância existentes para P. viridis, folha, suas preparações e constituintes.
Psychotria viridis Ruíz & Pavón, leaf, is a crucial element in the traditional plant-based preparation, known by the name “Ayahuasca tea”. Nowadays this preparation has been studied for its different potentially therapeutic effects, however in the available literature there is still a gap concerning botanical diagnosis of the plants that take part in the preparation. For this motive, this work attempts to do the botanical diagnose of 15 samples Psychotria viridis Ruíz & Pavón, leaf, being performed a macroscopical analysis, a microscopical analysis both through optic microscopy and scanning electron microscopy, as well as microscopical quantitative and histochemical analysis in order to enable identification and quantification of useful elements for diagnosis. Additionally, it is presented the results of a study which aimed to detect the chemical constituents of the PPB possibly containing P. viridis leaves, having adapted directed extraction techniques and chemical characterization techniques through characterization techniques using Thin-Layer Chromatography (TLC). All experimental work was carried out after research and compilation of bibliographic data of highest relevance available for P. viridis leaves, its preparations and constituents.
