Triterpenoids and phenolics from the fruiting bodies of Inonotus hispidus and their activations of melanogenesis and tyrosinase

Two new 24-methyl lanostane triterpenoids (1 and 2), and a new phenolic compound (7), along with nine known compounds (3-6, and 8-12), were isolated from the fruiting bodies of Inonotus hispidus. All of the isolates were evaluated their activations of melanogenesis and tyrosinase in B16 melanoma cells.
