Figure 1From: Inhibition of melanogenesis and antioxidant properties of Magnolia grandiflora L. flower extract 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.Back to article page
