Biometric measurements of leaves and fruits from Algerian atlas pistachio province Ouled Djellel (Biskra) Ain Oussara and Messaad (Djelfa), were realized and compared. The results showed significant differences between different varieties which may be due to climatic factors. Essential oils of the leaves and the oleoresin from Ouled Djellel were extracted and examined then their antimicrobial activity was tested on five bacterial strains of clinical origin ( Staphylococcus aureus , Escherichia coli , Escherichia coli ATCC 25922, Klebsiella pneumoniae , Pseudomonas aeruginosa ) and a yeast strain ( Candida albicans ). The oleoresin has provided an essential oil yield of 25% and rich on α-pinèn, leaves have presented a yield of 0,24% when the terpinèn-4-ol was in high percentage, both essential oils were characterized of an antimicrobial effect on the most microbial strains.
