Relationship and whitening effects of saponions. (A) Relationship between different saponins and the mixtures and (B) Inhibition effects of different ginsenosides at the same concentration of 0.1 mg/mL on B16 cell and (C) The Melanin content of B16 cell after treated with different saponin at the same concentration of 0.1 mg/mL. All the groups were treated with 20 nM α-MSH except the blank group. The data are expressed as a mean value ± SD of three independent experiments. Data analyses were all one-way t-tests for comparisons with the CONTROL group, ∗P ≤ 0.05, ∗∗P ≤ 0.01, ∗∗∗P ≤ 0.001, ∗∗∗∗P ≤ 0.0001.
