Root extracts of Angelica gigas Nakai were tested to see the possibility for functional cosmetic agents. From ethanol extraction method, 97% of decursin and decursinol angelate was obtained, and concentration ratio of decursin to decursinol angelate was about 3:2. To test possibility as a functional cosmetic agent, DPPH free radical scavenging assay, UVA/B absorption, tyrosinase inhibition assay, melanogenesis inhibition assay, elastase inhibition assay and MTT assay were done. Root extracts of Angelica gigas Nakai showed $45.2{\pm}3.9%$ tyrosinase inhibition of tyrosine, and $24.2{\pm}12.0%$ melanin inhibition at $15{\mu}g/ml$ extract concentration, so that it indicated good whitening effect. DPPH free radical scavenging activity was $40.9{\pm}9.1%$ at $240{\mu}g/ml$ concentration, which is relatively good. Anti-wrinkle effect was poor such that it was $12.7{\pm}6.8%$ at $100{\mu}g/ml$. UVA/B absorption was also negligible. From the research, root extracts of Angelica gigas Nakai showed good potential as a whitening agent.
