Abstract:	This research is part of a larger study of the Brazilian species that are commonly referred to as quinas and are usually used as substitute of Cinchona species. The purpose of the present study was the botanical characterization of the whole and powdered stem bark of Polyouratea hexasperma (A. St.-Hil.) Tiegh., Ochnaceae, by morphological and anatomical description, and the analysis of its chemical profile. The external texture of the bark, the whitened pit in the inner bark and the presence of cristarque cells, as well as the shape and arrangement of other lignified cells, are the most important macroscopic and microscopic features for the characterization of the bark. Chlorogenic and cafeic acids were detected in the chemical analysis and can also be used in the identification of the bark.
