Inhibitory Effect of Various Extracts of Ricinnus Communis on Human Pathogens

Extracts of Riccinus communis were made in mid-polar solvent acetone and non-polar solvent, petroleum ether by using fresh stem, leaves and tender fruits. Bioassay and Minimum Inhibitory Concentration (MIC) was done against various gram positive and gram negative bacteria by agar cup method. Significant activity was found in all acetone extracts against mainly gram positive bacteria and some gram negative bacteria. MIC of all potent extracts was at 0.5 mg/ml against most of the susceptible microorganisms.
