Hosta longipes and its Active Compounds Control Melanogenesis in B16F10 Melanoma Cells

Hosta longipes (FR. et SAV.) MATSUMURA (Liliaceae) is an edible vegetable in Korea and widely distributed throughout Korea, China, and Japan. It is called “Bi‐Bi‐Chu” in Korea, and its young leaves are consumed raw as a salad. This plant has been used as a Korean traditional medicine for the treatment of swelling, inflammation and snake bites. In this study, we confirmed the whitening effects of Hosta longipes ethanol extract in B16F10 cells and identified that hexane fraction had the highest whitening effect by serial solvent fractionation. To identify the active ingredients in the hexane fraction we performed column chromatography and it was confirmed that linolenic acid and linoleic acid reduced the melanin contents in B16F10 cells. The anti‐melanogenesis potential of linolenic acid and linoleic acid in Hosta longipes will provide insight into the development of new skin whitening products.
