Skin pigmentation involves multiple processes, including melanin synthesis, transport, and melanosome release. Melanin content determines skin color and protects against UV radiation-induced damage. Autophagy is a cooperative process between autophagosomes and lysosomes that degrades cellular components and organelles. In the present study, B16F1 cells were treated with Rhizoma Arisaematis extract (RA) and assessed for pigmentation and autophagy regulation. RA treatment suppressed the α-MSH-stimulated increase of melanogenesis and down-regulated the expression of tyrosinase and TRP1 proteins in B16F1 cells. In addition, autophagy was activated in RA-treated cells. Inhibition of autophagy reduced the anti-melanogenic activity of RA in α-MSH-treated B16F1 cells. We identified schaftoside as an effector molecule by LC-MS analysis of RA. Consistently, treatment of schaftoside showed anti-melanogenic effect and induced autophagy activation in B16F1 cells. Inhibition of autophagy by 3â¯MA treatment reduced the anti-melanogenic effect of the schaftoside and recovered expression level of melanogenesis regulators in α-MSH-treated B16F1 cells. Taken together, our results suggest that schaftoside from RA inhibits skin pigmentation through modulation of autophagy.
