The 50% inhibitory concentration value of ursolic acid against the viability of T. gondii and T. gondii–infected cells measured by the MTT assay.

The Tested Compound	Structure (C30H48O3)	The IC50 (µg/mL) of Ursolic Acid against T. gondii	The IC50 (µg/mL) of Ursolic Acid against T. gondii–Infected Cells
Ursolic acid (UA)		94.62	162.25

The anti-T. gondii effect of ursolic acid against the proliferation and the viability of T. gondii and T. gondii–infected cells was measured using the MTT assay. They were incubated with different concentrations (25–200 µg/mL) of the compound at 37 °C for 24 h respectively. IC₅₀ (50% inhibitory concentration value of UA against the survival rate of T. gondii and T. gondii–infected cells). The results were carried out three times independently.
