RESUMEN
Objective To study the antibiotic activities of leaf extract of Stellera chamaejasme L on the skin. Methods Activities of the leaf extract on Trichophyton gypseum and Staphylococcus aureus was examined by antibiotic susceptibility paper disk method and tube double dilution method. Results When extracted by 95%ethanol,the extract from Stellera chamaejasme L at 100 mg·mL-1 formed an inhibition zone with the diameter of 12. 8 mm for Staphylococcus aureus and 12. 0 mm for Trichophyton gypseum. When extracted by dichloromethane,the minimum inhibitory concentration( MIC)of the extract from Stellera chamaejasme L was 0. 25 mg·mL-1 for Staphylococcus aureus and 0. 50 mg·mL-1 for Trichophyton gypsem. Conclusion Leaf extract of Stellera chamaejasme L has an antibacterial activity against Staphylococcus aureus and Trichophyton gypseum and the antibacterial activity against Staphylococcus aureus is stronger.
