초록

본 연구에서는 명월초 추출물의 메탄올 분획물과 아글리콘 분획물을 제조하였고, 이들에 대한 항산화 활성을 측정하였다. 항산화 활성 측정은 1,1-diphenyl-2-picrylhydrazil (DPPH) radical을 이용한 프리 라디칼 소거활성, 루미놀 발광법을 이용한 활성산소 소거활성(총 항산화능) 및 활성산소($^1O_2$ 등)로 유도된 세포손상에 있어서 세포 보호 효과를 측정하였다. 명월초 추출물의 프리 라디칼 소거활성($FSC_{50}$)은 메탄올 분획이 $90.25{\mu}g/mL$이고, 당을 제거한 아글리콘 분획은 $81.38{\mu}g/mL$를 나타내었다. 총 항산화능($OSC_{50}$)은 메탄올 분획 $16.96{\mu}g/mL$, 아글리콘 분획 $12.30{\mu}g/mL$로, 프리 라디칼 소거활성 및 활성산소 소거활성 모두 아글리콘 분획에서 큰 활성을 나타내었다. $^1O_2$로 유도된 사람 적혈구의 세포손상에 대한 보호 효과는 ${\tau}_{50}$ 값으로 확인하였다. $5{\mu}g/mL$ 농도에서 메탄올 분획 및 아글리콘 분획의 ${\tau}_{50}$이 각각 36.7 및 76.1 min으로, 비교 물질인 (+)-${\alpha}$-tocopherol (35.4 min)과 비교했을 때 아글리콘 분획이 약 2배 더 큰 세포 보호 효과를 나타내었다. 이러한 결과들은 명월초 추출물의 아글리콘 분획물이 항노화 관련 화장품에 있어서 항산화소재로서 응용가능성이 있음을 시사하였다.

In this study, the methanol fraction and aglycone fraction were made from Gynura procumbens (G. procumbens) extracts and their antioxidative effects were investigated. The free radical scavenging activity (1,1-diphenyl-2-picrylhydrazyl, DPPH), total antioxidant capacity by luminol-dependent chemiluminescence assay, and the protective effects against reactive oxygen species (ROS) in erythrocytes were measured to evaluate the antioxidative activities of the extracts. Free radical scavenging activities ($FSC_{50}$) of the methanol fraction and aglycone fraction were 90.25 and $81.38{\mu}g/mL$, respectively. Total antioxidant capacities ($OSC_{50}$) of the methanol fraction and aglycone fraction were 16.96 and $12.30{\mu}g/mL$, respectively. The free radical scavenging activity and total antioxidant capacity of the aglycone fraction were greater than those of methanol fraction. The cellular protective effect on the $^1O_2$-induced cellular damage of human erythrocytes was confirmed by ${\tau}_{50}$ value. The ${\tau}_{50}$ value of the methanol fraction and aglycone fraction were 36.7 min and 76.1 min, respectively in $5{\mu}g/mL$, and the aglycone fraction showed about 2 times higher cellular protecive effect than (+)-${\alpha}$-tocopherol (35.4 min). These results indicate that the aglycone fraction of G. procumbens extracts has application possibility as antioxidant ingredient of cosmetic.
