Phytochemical and Antibacterial Investigations of the Extracts and Fractions from the Stem Bark of <i>Hymenaea stigonocarpa</i> Mart. ex Hayne and Effect on Ultrastructure of <i>Staphylococcus aureus</i> Induced by Hydroalcoholic Extract

<table>Chromatographic fingerprints from <i>Hymenaea stigonocarpa</i> stem barks. Hydroalcoholic extract (HE) + astilbin (98%), hydroalcoholic extract (HE), ethanolic extract (EE), and aqueous fraction (AF) obtained by HPLC DAD at 280 nm. Each chromatographic peak appears with its corresponding retention time. UV spectrum pattern derivatives flavonoids (A, C, and D) identified as astilbin (B).</table>
