Two new 24-methyl lanostane triterpenoids,hispindic acids A and B(1 and 2),and a new phenolic compound,hispinine(7),along with nine known compounds(3-6,and 8-12),were isolated from the fruiting bodies of Inonotus hispidus.Their structures were elucidated based on the extensive analysis of spectroscopic data(NMR and HRMS).Hispindic acid A(1) possesses an unusual formyl group at C-30.Compounds 1,3-4,and 8 showed stronger activate abilities of melanogenesis and tyrosinase in B16 melanoma cells than those of positive control,8-methoxypsoralen,at 50 μmol/L
