Different species of Baccharis are commonly known as carqueja and are used indistinctly in the traditional medicine as stomachic and diuretic. This research aimed to carry out the drug analysis of Baccharis dracunculifolia DC., B. articulata (Lam.) Pers., B. cylindrica (Less.) DC. and B. gaudichaudiana DC. In general, B. dracunculifolia showed the highest results of water content, essential oil and loss on drying, while B. articulata showed the highest foam and bitter indices, ash and water soluble extractive results. Some components of the essential oil appeared in the four species, although each one showed a charateristic chromatographic profile by TLC analysis.
