ABSTRACT
The species Mikania glomerata Sprengel, popularly known in Brazil as “guaco”, is widely used as an expectorant to treat respiratory diseases. Its pharmacological activity is mainly attributed to coumarin. The results showed that the method for determining coumarin presented linearity from 0.05 to 0.8 mg mL-1. It was considered selective, accurate, and precise according to the specific resolution from ANVISA, the Brazilian regulatory agency. The proposal of a rapid method for the determining coumarin in extracts of guaco is interesting for routine industrial quality control in order to obtain standardized, efficient, and safe phytotherapic medicines.
