Antioxidant Activity of Five Medicinal Plants Extrats Used for Management of Bacterial Diseases in Burkina Faso

摘要

The plant biodiversity of Burkina Faso abounds with countless plants, some of which are of proven medicinal interest. The objective of this work is to highlight five (5) medicinal plants including Psidium guajava , Euphorbia hirta , Combretum micranthum , Eucalyptus camaldulensis and Terminalia avicennioides used in the management of bacterial infections. Recent work shows that many microbial pathologies, particularly bacterial and viral infections, are linked to oxidative stress induced by the production and development of free radicals. In this study, we established the chemical profile of the extracts in therapeutic compounds of interest such as phenolic compounds. The antioxidant activity of the decocted extracts of these five plants was studied by several methods including the DPPH tests, the ABTS test and the lipid peroxidation test. Significant and interesting results were obtained.
