참당귀 뿌리 추출물에서 기능성 화장품소재를 개발하고자 하였다. 기기분석시험을 통하여 참당귀 뿌리 추출물에는 유효성분으로서 decursin과 decursinol angelate가 약 97%로 매우 고농도로 존재하였으며 그 비가 약 3:2로 나타났다. 화장품소재 시험으로는 항산화(DPPH free radical scavenging assay), 미백(Tyrosinase inhibition assay, Melanogenesis inhibition assay), 주름개선(Elastase inhibition assay), 자외선 흡수 및 안전성 시험(MTT assay)이 실시되었다. 참당귀 뿌리 추출물은 $15{\mu}g/ml$의 농도에서 tyrosine에 대한 tyrosinase 저해효과가 $45.2{\pm}3.9%$, melanin 생성억제 효과가 $24.2{\pm}12.0$로 미백효과가 우수하였다. 항산화효과는 $240{\mu}g/ml$의 추출물농도에서 DPPH free radical 소거율이 $40.9{\pm}9.1%$로 비교적 우수하였다. 주름개선 효과는 $100{\mu}g/ml$의 추출물농도에서 $12.7{\pm}6.8%$로 낮았으며, 자외선 흡수효과도 거의 없었다. 따라서 본 연구를 통하여 참당귀 뿌리 추출물은 화장품용 미백소재로서 가능성을 보여주었다.

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.
