This research is part of a larger study of the Brazilian species that are commonly referred to as “quinas” and used as substitute of Cinchona species. In this study, we have performed the botanical characterization of the stem bark of Remijia ferruginea (A. St.-Hil.) DC., Rubiaceae, by morphological and anatomical description, and the analysis of its chemical profile. Stem bark is thin and has the color and the texture of its external and internal surfaces as diagnostic features. Types and sizes of sclerified cells in the cortical parenchyma and in the secondary phloem are important features for analysis of the transversal sections and in the macerate. Alkaloids, flavonoids and chlorogenic acid were detected in the chemical analysis for TLC. These standard references can be used in the quality control of the bark of quinas
