RESUMO: O mercado brasileiro de fitoterápicos encontra-se em crescente expansão, porém a falta de padronização e a má qualidade da matéria-prima vegetal constituem um problema crucial na produção de fitoterápicos de qualidade. Neste trabalho, foram avaliadas drogas vegetais constituídas de folhas (amostras A, B, C) e tinturas (amostras D, E, F) de guaco, adquiridas no Mercado Central e em farmácias de manipulação de Belo Horizonte, respectivamente. Realizaram-se testes físico-químicos de caracterização organoléptica, determinação de matéria estranha, teores de água e cinzas totais para as amostras de drogas vegetais e caracterização organoléptica, medidas de pH e de densidade para as amostras de tinturas. Foram obtidos os perfis cromatográficos por CCD e CLAE-FR e fez-se a quantificação da cumarina (marcador químico), por CLAE-FR. As amostras analisadas apresentaram um ou mais dos parâmetros avaliados fora dos valores preconizados pela farmacopéia brasileira, evidenciando-se a necessidade da realização do controle de qualidade de matérias-primas vegetais, para se obter medicamentos fitoterápicos de qualidade, eficientes e seguros.Unitermos: Guaco, controle de qualidade, cumarina, quantificação, CLAE-FR.ABSTRACT: "Evaluation of the quality of commercial samples of leaves and tinctures of guaco". The Brazilian market of herbal medicine is in increasing expansion; however, the lack of standardization and the bad quality of the plant raw materials constitute a crucial problem for the production of quality herbal medicines. In this work, herbal drugs consisting of leaves (samples A, B, C) and tinctures (samples D, E, F) of guaco purchased in the Central Market and from pharmacies in Belo Horizonte, respectively, were evaluated. Physical-chemical tests such as organoleptic characterization, determination of foreign matter, total ash and water content were performed on the samples of herbal drugs. The organoleptic characterization, measures of pH and density of the tincture samples were also determined. TLC and RP-HPLC profiles of the herbal drugs and tinctures were obtained and the quantification of coumarin (used as a marker compound) by RP-HPLC was determined. The analyzed samples showed one or more of the evaluated parameters outside of the values recognized by the Brazilian Pharmacopoeia. This demonstrates the need for the quality control of the plant raw materials, in order to guarantee quality and safety in herbal medicine.
