Abstract
Qutran oil (Olea europaea) extracted as medicinal plants extracted has a great activity against four fungistrains. Aspergillus (flavus, fumigatus, niger) and Candida albicans throughout using agar well diffusion in our investgation. Results showed that, tar oilhas antifungal effects against studied strains. Inhibition growth rate was from 16.33 to 46.00 mm. and also has positive activities against investagated organisms more than traditional antibiotics either amphoteracin B or Nystatin. A. fumigatus was mainly susceptible fungi followed by A. niger while A. flavus has the most resistant fungi with inhibition zone (16.33 mm). Wood tar oil, Olea europaea, given a high DPPH radical scavenging activity 79.10% compared to ascorbic acid.

Summary
Olive tree (Olea europaea) is aperennial plants which were cultivated for many purposes such as oil, wood, leaf. It has droughtresistant, disease and fire-resistant properties. The side effects of these drugs, searching about new natural plant alternatives with desirable side effects become urgent for solving the traditional problems of using anti-biotic against many pathogens. Extracts of some plant species have rich component of such aromas materials and could be used as antimicrobial agents. There were many studies on plant extracts antimicrobial effects. Our invention given a new approach for tar oil could using as antifungal and antioxidant agents against many pathogenic
