From: Investigation of antioxidant and antimicrobial activities of Euclea schimperi leaf extracts
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
