To discover an active skin depigmenting agent, we isolated a novel inhibitor of melanin biosynthesis from the methanol extract of Erigeron breviscapus using a bioactivity-guided fractionation and identified it as (2Z,8Z)-matricaria methyl ester by means of spectroscopic analysis. The compound showed strong whitening activity in melan-a cells. Compared with arbutin (IC50=740μM) as a positive control, the depigmentation IC50 value for (2Z,8Z)-matricaria methyl ester was 10.7μM. Moreover, its inhibitory effect on tyrosinase, the key enzyme of melanogenesis, was examined using in vivo and in vitro tyrosinase assay and Western blot. Western blot analysis revealed that expression of tyrosinase and tyrosinaserelated proteins 1 and 2 (TRP1 and TRP2) was decreased. The results indicate that (2Z,8Z)-matricaria methyl ester isolated from Erigeron breviscapus is a promising compound that could be useful for treating hyperpigmentation as skin-whitening agent.
