Olea dioica Roxb. is a very important ethno medicinal evergreen tree grown abundantly in Western Ghats, India. This plant parts used by tribal people in sidda treatment. Studies were conducted on the anti-microbial properties of compound extracted from Olea dioica Roxb. Which was collected from selected parts of the Western ghats, Karnataka in April 2014. The present study was conducted to study the effectiveness of the plant crude extract against some animal and plant pathogenic microbes. Antimicrobial activity was assessed by agar well diffusion method against nine bacterial strains. The crude extracts (pet.ether, chloroform and methanol crude extracts) tested against 9 bacterial strains (3 plant pathogenic and 6 animal pathogenic). The results showed that the only methanoliccrude extract of Olea dioica Roxb. was effective against the all the microbes with fewer effect on the microbes by other two crude extracts (Petroleum ether and chloroform).
