Abstract
The objective of this study was to conduct phytochemical characterization and biological evaluation of Hymenaea eriogyne. Crude extracts and fractions from the bark, leaves and pods, were obtained for phytochemical screening by TLC and HPLC, and evaluation of antibacterial and antioxidant potential. Chromatographic data revealed the presence of several metabolites, notably from the flavonoid class. HPLC analysis confirmed the presence of the flavanonol astilbin (taxifolin 3-O-ramnoside) and other flavonoids derived from aglycone taxifolin. In addition, it was possible to quantify phytochemical markers in the extracts and fractions, which showed an increased content of flavonoid and catechin derivatives in the fraction. Better results of the minimum inhibitory/bactericidal concentrations were obtained with extracts and fractions from bark. In the antioxidant activity using the DPPH method, the enriched bark fraction presented an IC50 of 34.46 µg/mL. These results contribute to the continuity of studies on the chemical and biological composition of the species.
