Abstract

In this study, we performed anti-oxidation, whitening, cell recovery and anti-inflammation effects with Alisma orientale to evaluate the cosmeceutical properties. Alisma orientate extract (30, 70, 100 % MeOH) exhibited a significant tree radical scavenging effect against 1,1-diphenyl-2-picryl hydrazine (DPPH) radical generation and showed tyrosinase inhibition effect in a dose dependent manner (over 0.5% concentration). In cell proliferation assay using human fibroblast, it didn't show any proliferation effect but showed safety from cytotoxicity under 0.05% concentration. For whitening assay, we evaluated the melanin synthesis rate using B16 melanocyte and it showed a significant inhibitory effect (up to 40% under 0.05% concentration). After major screening assay, we separate 3 fractions from Alisma orientate extract by MPLC and performed cell recovery assay, melanin synthesis inhibition assay and anti-inflammatory assay. The third fraction showed a cell recovery effect over 30% against radical damage and remarkable repression in melanin synthesis and COX-2 synthesis.

본 연구는 택사의 화장품 원료로서의 특성을 알아보기 위하여 화장품의 기능들인 항산화, 미백, 세포 손상 회복 및 항염증과 관련된 다양한 실험을 실시하였다. 30, 70, 100% MeOH 용매로 추출한 택사 추출물들은 DPPH법으로 실시한 free radical scavenging assay에서 좋은 활성을 보여주었고, tyrosinase 활성 억제 시험에서도 0.5% 이상의 농도에서 농도 의존적인 활성을 보여주었다. Human fibroblast를 사용한 proliferation assay (MTT assay)에서 각 용매 추출물들은 별다른 효과를 보여주지 못했고 0.05% 이하의 농도에서는 세포 독성으로부터 안전하다는 것을 알 수 있었다. Bl6 melanocyte를 사용한 melanin 생성 억제시험에서 각 용매별 추출물은 독성으로부터 안전한 0.05% 이하의 농도에서 melanin 생성을 40% 이상 억제하는 높은 활성을 보여주었다. 이후 우리는 택사 추출물의 MPLC분리 분획을 실시하여 세 가지 분획을 얻었으며 이들을 대상으로 세포 손상 회복시험과 melanin생성 억제 시험, 염증인자 생성 억제 시험을 실시하였다. 그 결과 분획물들 중 3번 분획물이 세포 손상 회복을 30% 이상 올려주는 좋은 결과를 보여주었고, melanin 생성 억제 시험과 COX-2 생성억제에서도 주목할만한 결과를 보여주었다.
