The objective of this work was to verify the influence of different drying processes on the levels of quercetin of the aerial parts of Baccharis articulata (Lam.) Pers., Asteraceae, as well as the evaluation of the in vitro antioxidant activity of these extracts. We demonstrated that the highest concentration of this flavonoid was detected in oven-dried samples, although there no significant difference in their pharmacological activity of all analyzed samples could be shown.
