Effect of M. grandiflora L. flower extract on B16F10 cell viability. Cells were treated with various concentration of flower extract (10, 12.5, 15, 17.5, 20%; v/v) for 24 h and the cell viability was measured by MTT assay. Results are expressed as percentage of cell viability relative to control. Data are presented as mean ± S.D. Values are significantly different by comparison with control. ** p < 0.01.
