초록

씀바귀 80% 에탄올 추출물의 추출 수율은 12.6%를 나타내었으며, 추출물에 함유된 총 페놀 및 플라보노이드 함량은 각각 $4.01{\pm}0.63$ GAE mg/g 와 $0.05{\pm}0.01$ RE mg/g을 나타내었다. 3가지의 항산화 측정 모델(DPPH, ABTS, reducing power)을 통하여 씀바귀 추출물의 항산화 활성을 측정한 결과 씀바귀 추출물은 동일 농도에서 양성대조군으로 사용된 ascorbic acid보다는 낮은 항산화 활성을 가진 것으로 생각된다. 씀바귀 에탄올 추출물의 50, 100, 200 및 $400{\mu}g/mL$ 농도범위에서 세포독성을 측정한 결과, 대조군과 유의적인 차이가 없었으므로(p<0.05) 씀바귀 에탄올 추출물을 50, 100, 200 및 $400{\mu}g/mL$ 농도로 하여 항비만 활성을 평가한 결과 씀바귀 추출물을 처리한 지방세포는 모든 농도 범위에서 대조군과 비교하여 Oil red O 시약에 의하여 염색된 지방구는 유의적으로 적은 것으로 나타났다(p<0.05). 이상의 결과로부터, 씀바귀 추출물은 항산화 활성 및 지방세포 분화억제 효능을 갖으며, 천연물 유래 항산화제로써 활용가능성이 높은 것으로 기대된다.

The aim of this study was to evaluate the total phenol, total flavonoids contents and antioxidant activity of 80% ethanolic extract from Ixeris dentata Nakai(IDE) as well as to assess the lipid accumulation during adipogenesis of 3T3-L1 cells. The results demonstrated that the total phenolic and flavonoids contents of the IDE were $4.01{\pm}0.63$ GAE mg/g and $0.05{\pm}0.01$ RE mg/g, respectively. The antioxidative activities of the IDE were significantly increased in a dose dependent manner on DPPH(1,1-Diphenyl-2-picrylhydrazyl) radical scavenging, ABTS(2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)diammonium salt) radical scavenging, reducing power value. During adipocyte differentiation, IDE significantly inhibited lipid accumulation compared with the control cells. These results indicated that the anti-adipogenesis effect of Ixeris dentata Nakai could be attributed to phenolic compounds that may potentially inhibit ROS(reactive oxygen species) production.
