초록

선구 연구로부터 저자들은 제주 자생 식물 추출물의 항산화 및 세포보호 효과에 대한 결과의 일부를 이미 보고하였으며, 본 연구에서는 제주도에서 자생하는 나머지 37종의 식물 추출물에 대한 항산화, 미백 그리고 주름생성억제 효과를 측정하였다. 항산화 효과는 1,1-diphenyl-2-picrylhydrazyl radical(DPPH)을 이용한 free radical 소거 활성 측정, $Fe^{3+}-EDTA/H_2O_2$ 계에서 생성된 활성산소종으로 인한 luminol의 화학발광을 이용한 소거 활성, 사람 적혈구를 대상으로 하여 rose-bengal로 증감된 활성산소에 대한 세포보호 효과를 측정하였다. 미백 및 주름억제 효과측정으로는 각각 tyrosinase, elastase의 활성 저해 효과를 측정하였다. 실험결과, free radical의 소거 활성($FSC_{50}$)은 소귀나무 수피(Myrica rubra, 5 ${\mu}g/mL$), 광대싸리 수피(Securinega suffruticosa, 8 ${\mu}g/mL$)에서 높게 나타났고, 활성산소 소거 활성($OSC_{50}$)은 상수리나무 잎(Quercus acutissima)과 광대싸리 수피(Securinega suffruticosa)에서 0.009 ${\mu}g/mL$로 높게 나타났으며, 세포보호 효과(${\tau}_{50}$)는 50 ${\mu}g/mL$에서 광대싸리 수피(Securinega suffruticosa, 895 min), 버드나무 줄기(Salix koreensis, 640 min)에서 크게 나타났다. 200 ${\mu}g/mL$에서 tyrosinase의 활성 저해 효과($IC_{50}$)는 소귀나무 수피(Myrica rubra, 77.8%), elastase의 활성 저해 효과($IC_{50}$)는 버드나무 줄기(Salix koreensis, 76.2%)에서 큰 효과가 나타났다. 결론적으로 광대싸리 수피, 소귀나무 수피, 상수리나무 잎, 버드나무 줄기, 동백나무 잎/줄기 추출물은 기능성 화장품 제조를 위한 원료로 사용하기에 충분한 가능성이 있음을 확인할 수 있었으며, 향후에 제품화를 위하여 좀 더 다양한 연구들이 필요하다고 사료된다.

In the previous study, we reported the antioxidative and cellular protective effects of Jeju native plant extracts. In this study, we investigated the anti-oxidative, anti-wrinkle and whitening effects of new 37 plant extracts collected from self-growing plants in Jeju island. Their anti-oxidant activities were measured by the 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical scavenging assay and reactive oxygen species(ROS) scavenging assay in $Fe^{3+}-EDTA/H_2O_2$ system. The cytoprotective properties of 37 plant extracts were assessed in the rose-bengal sensitized photohemolysis of human erythrocytes. The inhibitory effect of 37 plant extracts on tyrosinase were investigated to assess their whitening efficacy. Finally, their anti-elastase activities were measured to predict the anti-wrinkle efficacy in the human skin. The results showed that the extracts of Myrica rubra stem bark and Securinega suffruticosa have the free radical scavenging activity($FSC_{50}:\;5,\;8{\mu}g/mL$, respectively), and the extracts of Quercus acutissima leaf and Securinega suffruticosa stem bark have the prominent ROS scavenging activity($OSC_{50}:\;0.009{\mu}g/mL$). Photohemolysis of erythrocytes in the presence of rose-bengal as a sensitizer was inhibited by the extracts of Securinega suffruticosa stem bark and Salix koreensis stem(${\tau}_{50}$, 895 min, 640 min at 50 ${\mu}g/mL$, respectively. Myrica rubra stem bark extract(77.8% at 200 ${\mu}g/mL$) and Salix koreensis stem extract(76.2% at 200 ${\mu}g/mL$) also have the inhibitory effect on tyrosinase and elastase activities, respectively. These results indicated that the stem park of Myrica rubra, Securinega suffruticosa, and Camellia japonica, the stem of Salix koreensis, and the leaf of Quercus aqutissima and Camellia japonica could have e benefitial effects when they are added as ingredients in cosmetics.
