PROPOLIS: ANTIMICROBIAL ACTIVITY AND CHEMICAL COMPOSITION ANALYSIS

Over the last few years, propolis has been object of many studies conducted around world, and its biological properties chemical composition have widely investigated. The present study focuses on evaluation antimicrobial activity as well an examination two samples from Eastern Algeria coming commune El Mechrouha Ouled Driss in wilaya Souk-Ahras. are tested for their power by undertaking agar diffusion technique eight pathogenic microbial strains (six bacterial fungal strains) which are: Escherichia coli, Klebsiella pneumonia, Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus agalactiae, thoraltensis, , Candida famata Aspergillus niger. results obtained clearly show impact susceptibility Gram-positive bacteria (S. agalactiae S. aureus), species (C. A. niger). analysis ethanolic extracts UV-visible absorption spectrometry thin layer chromatography showed that Algerian is wealthy phenolic compounds, high performance liquid allowed identification four polyphenols (Gallic acid, Caffeic Quercetin Catechin). These outcomes permitted a first assessment comparable components compositions.
