title: Phenolic content, antioxidant capacity and antimicrobial activity of leaf extracts from Pistacia atlantica.
abstract: The aim of this study was to investigate the secondary metabolites related to Pistacia atlantica Desf as well as their biological activities. Results show that using ethanol as a solvent exhibited the highest content of total phenolics and flavonoids (68.23 mg GAE g-1of DW and 44 mg RE g-1of DW), followed by aqueous one (20.07 mg GAE g-1of DW and 15 mg RE g-1of DW). Good correlation (Data not shown) was obtained between the DPPH radical-scavenging activities and total phenolics contents. Many similarities were observed between the results of the DPPH (IC50= 32 and 200 μg mL-1) and ABTS (IC50= 42 and 300 μg mL-1) assays. All tested extracts contained phenolic compounds exhibited an antimicrobial effect against Gram-positive and Gram-negative bacteria. Further, researches for identification and purification of phenolic compounds are required.
