Abstract
: Phenolic compounds are frequently found in the specific tissues in the leaves and stems of Baccharis species . However, only a few species of the genus have been studied in recent years, including B. erioclada . This study evaluates the in vitro antioxidant potential of B. erioclada crude extract and its fractions. Phytochemical studies, including quantification of total phenolics and flavonoids have also been carried out. Crude extract presented higher antioxidant capacity since it showed lower values of IC50 or greater reductive capacity compared to the fractions. The total phenolic compounds and flavonoids in the HIGHLIGHTS
