Effects of Prunella vulgaris var. lilacina on RAW264.7 cells as determined by the MTT assay. Cells were treated with solvent fractions of Prunella vulgaris var. lilacina at different concentrations (10, 50 and 100 μg/mL). After treatment for 24 h, cell viability was measured with the MTT assay. Values are the mean ± SEM; different marks within treatments indicate significant differences at *p < 0.05 compared to the PBS group.
