Desenvolvimento de métodos cromatográficos para a padronização do extrato de Eugenia speciosa Cambess

The use of medicinal plants is common in many Brazil's ethnic groups, because the diversity of plant species in the country is large. But the utilization of these plants as standardized herbal doesn't occur with de same frequency, due the lack of studies related to these therapies, classified as alternatives. Due to the high cost of some synthetic medicines for the treatment of chronic diseases, phytotherapy is a low-cost alternative and efficient, since the phytomedication has proven scientific studies and its production meets strict criteria for manufacturing and quality control to ensure its safety and efficacy. Among the medicinal species used for the treatment of chronic diseases, such as pain and inflammation, is Eugenia speciosa Cambess, popularly known as the bush laranjinha. Against this context, this paper held preliminary studies and developed the chromatographic profile of the hydroalcoholic extract of the leaves of E. speciosa by High Performance Liquid Chromatography coupled to photodiode array detector (CLAE-DAD). Preliminary qualitative results and the chromatographic profile have identified some metabolites classes present and some constituent as: homogentisic acid, homorientina, isovitexin and quercetrin
