Seasonal Effect on the Biological Activities of Litsea glaucescens Kunth Extracts

Figure 5

Antibacterial activity of L. glaucescens extracts against Staphylococcus aureus (SLGE: spring L. glaucescens extract; SULGE: summer L. glaucescens extract). Bacterial cell cultures were treated with different concentrations of L. glaucescens extracts during 48 h. ◆: 1000 μg/mL; ▼: 800 μg/mL; ▲: 600 μg/mL; ■: 400 μg/mL; ●: 0 μg/mL; ×: gentamicin. Control bacterial cultures were incubated with DMSO (0.8–2%). Gentamicin (12 μg/mL) was used as positive control. All values represent mean ± standard deviation.
