The inhibitory effect of ursolic acid against the growth and the proliferation of T. gondii-infected cells.
| Infection Ratio of T. gondii (MOI) | Incubation Time | Concentrations (µg/mL) | The Survival Rate (%) of T. gondii-Infected Cells | |
|---|---|---|---|---|
| Ursolic Acid (UA) | Sulfadiazine (SF) | |||
| Cells:T. gondii = 1:5 | 24 h | 0 | 100.00 ± 2.28 | 100.00 ± 3.46 |
| 25 | 92.35 ± 2.74 | 94.26 ± 1.82 | ||
| 50 | 85.52 ± 1.55 | 91.35 ± 1.64 | ||
| 100 | 67.61 ± 1.87 | 77.58 ± 3.45 | ||

T. gondii-infected cells were incubated with different concentrations (25–200 μg/mL) of ursolic acid (UA) and sulfadiazine (SF) for 24 h respectively, and their survival rates were measured using the MTT assay. The results were expressed as a percentage of the normal group, and all the results were presented as mean ± standard deviation (S.D.) of three independent experiments.
