In vitro Antibacterial Potential of the Oleoresin, Leaf Crude Hydroalcoholic Extracts and Isolated Compounds of the Copaifera spp. Against Helicobacter pylori

Abstract Helicobacter pylori is often related to severe clinical manifestations of infections and may increase an individual’s chance of developing stomach cancer. We are reporting the in vitro anti-H. pylori effects of several Copaifera spp. derivatives such as oleoresins, hydroalcoholic crude extracts from the leaves, and isolated compounds, by determining their Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) values. It was obtained promising MIC (MBC) values, ranging from 6.25 (12.5) to 100 (400) μg/mL, from 12.5 (25) to 100 (100) μg/mL, and from 3.12 (3.12) to 100 (100) μg/mL respectively, for Copaifera spp. oleoresins, leave crude hydroalcoholic extracts and isolated compounds. Therefore, all Copaifera spp. derivatives displayed promising antibacterial activities against H. pylori.
