Comparison of inhibition zone among crude extracts of Euclea schimperi leaves using different solvent (methanol and chloroform) against standard Gram-positive and Gram-negative bacteria. Standardized inoculums of the test organisms were inoculated into series of sterile tubes of 2 mL nutrient broth containing 500, 250, 125, 62.5 and 31.25 mg/mL of each extracts and incubated at 37 °C for 24 h. The methanol extract showed maximum antibacterial activity against S. aureus and P. aeuroginosa with diameter of 20.67 ± 1.53 and 17 ± 1 mm at concentrations of 500 mg/mL, respectively. Chloroform extract also exhibited antibacterial activity against S. aures and P. aeuroginosa with diameter of 15 ± 1 and 14.33 ± 0.58 mm at concentrations of 500 mg/mL, respectively
