ABSTRACT
The essential oil from the gum of Pistacia atlantica Desf. grown in Algeria was obtained by the hydrodistillation method; and its antimicrobial activities against the growth of clinical isolates of Staphylococcus aureus; Escherichia coli and Streptococcus pyogenes were evaluated using three different methods; agar disc diffusion and dilution broth methods and minimum inhibitory concentration (MIC) which was subsequently; determined. The results of the study revealed that essential oil resin of P. atlantica has antimicrobial activity against gram-positive and -negative bacteria which are resistant to commonly used antimicrobial agents; and they were considerably dependent on concentration

The antimicrobial activity and antioxidant properties of Pistacia lentiscus L. and Pistacia atlantica Desf (Anacardiaceae) leaves extracts were studied against eight bacteria; five moulds and yeast. A strong antifungal activity and a weak antibacterial activity were observed. They showed also a high reducing power capacity and a weak scavenging activity for superoxide anions (14.16for P. lentiscus and 19.3for P. atlantica)
