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.
