Abstract

Methods for preparation of hydroalcoholic extracts of "guaco" (Mikania glomerata Spreng.) leaves were compared: maceration, maceration under sonication, infusion and supercritical fluid extraction. Evaluation of these methods showed that maceration under sonication had the best results, when considering the ratio extraction yield/extraction time. A high performance liquidchromatography (HPLC) procedure for the determination of coumarin in thesehydroalcoholic extracts of "guaco" leaves is described. The HPLC method isshown to be sensitive and reproducible.
