Figure 5

Anti-hemolytic activities of alizarin and other anthraquinones.

The hemolysis of human blood by S. aureus MSSA 6538 was quantified in the presence of anthraquinone-related compounds at 10 μg/ml (a) or alizarin (0, 5, 10, or 20 μg/ml) (b) after incubation for 20 h. Pictures of spectrophotometer cuvettes are shown. At least two independent experiments were conducted. *P < 0.05 versus non-treated controls (None or 0).
