The objective of this study was to investigate the whitening effect of Salvia miltorrhiza Bunge water extract (SM-W) in human epidermal melanocyte (HEM). Mushroom tyrosinase inhibitory effect of SM-W was approximately 42% at $1,000{\mu}g/mL$. The HEM cellular tyrosinase and melanin synthesis inhibition activity were 26 and 25% at $5{\mu}g/mL$, respectively. Whitening related proteins and mRNAs including tyrosinase, tyrosinase related protein 1 (TRP-1) and TRP-2, and microphthalmia associated transcription factor were reduced by SM-W treatment. In addition, the cAMP expression inhibitory effect of SM-W was decreased by 41% at $5{\mu}g/mL$ concentration. These results indicated that Salvia miltorrhiza Bunge could be used to the possible utilization of functional cosmetic ingredients by confirming whitening activity related with melanin content.
