| Abstract: | Objective To study the antibacterial activity of extract of Ginkgo biloba leaves （EGb） on Staphylococcus aureus and E. coll. Method Antimierobial circle diameter and minimum inhibitory concentration （MIC） were used as the indexes to test the antibacterial effect of EGb. Results The antimicrobial circle diameter of EGb to Staphylococcus aureus was 16.5 mm, and MIC was 12.5 mg/mL. The antimierobial circle diameter of EGb to E. coli was 14. 5 ram, and MIC was 25 mg/mL. Conclusion EGb has certain effect on both Staphylococcus aureus and E. coli, showing a broad prospect of development and utilization as a natura] antibacterial agent and antiseptic. |
