Abstract

This study was to investigate the antioxidant and anti-inflammatory activity of leaf and stem of Ixeris dentate extract by hot water and 70% ethanol. The total flavonoid and polyphenol in 70% ethanol extract of leaf and stem of Ixeris dentate were significantly higher than those of hot water extracts. DPPH and ABTS free radical scavenging activity of 70% ethanol extract of leaf was higher than that of hot water extract of leaf. 70% ethanol extract of leaf was the highest on the DPPH and ABTS activity. Nitric oxide(NO) production of 70% ethanol extract was higher than that of hot water extract. According to this study, it was found that there was difference in physiological activity due to extraction solvents of each part of Ixeris dentate and it is believed that it can be used as an ingredient of functional foods using Ixeris dentate.

씀바귀(Ixeris dentata)의 잎과 줄기를 열수 및 70% 에탄올 추출하여 추출물의 농도별로 항산화 활성 및 항염증 효과에 미치는 영향을 검토하고자 실시하였다. 추출용매에 따른 총 flavonoid 및 polyphenol 함량은 씀바귀 잎과 줄기 모두 열수 추출물에 비해 70% 에탄올 추출물에서 높게 나타났다. DPPH 및 ABTS radical 소거활성은 씀바귀 잎의 70% 에탄올 추출물에서 열수 추출물에 비해 높게 나타났으나 줄기의 열수 추출물이 70% 에탄올 추출물보다 더 높은 활성을 보였다. 부위별 씀바귀 열수 추출물보다는 70% 에탄올 추출물에서 높은 NO 생성 억제 효과를 나타났다. 본 연구를 통하여 씀바귀의 부위별 추출용매에 띠라 우수한 생리활성에 차이가 있는 것으로 나타났으며 씀바귀를 이용하여 건강 기능성 소재로 활용할 수 있을 것으로 사료된다.
