Abstract

In this study, the anti-inflammatory effect of supercritical carbon dioxide selective extracts, which extract decursin and decursinol angelate, the vital active ingredients of Angelica gigas Nakai, in high yield, was measured compared to that of ethanol extracts. To measure the anti-inflammatory effect, the production of nitric oxide(NO), an inflammatory mediator, and interleukin(IL)-6 and IL-8, inflammatory cytokines, was measured. NO production was measured by Griess assay on Raw 264.7 cells induced inflammatory response by lipopolysaccharide(LPS), and IL-6 and IL-8 production was measured by enzyme-linked immunoadsorbent assay(ELISA) on human keratinocyte cell line(HaCaT) cells induced inflammatory response by tumor necrosis factor(TNF)-α. The amount of NO production was suppressed outstandingly by the supercritical carbon dioxide extracts compared to the ethanol extracts. The amount of IL-6 and IL-8 production was increased by the ethanol extracts, whereas statistically significantly inhibited by supercritical carbon dioxide extracts at the concentration of 6.25 ㎍/mL(P<0.01). Through these results, we confirmed that the supercritical carbon dioxide selective extracts of Angelica gigas Nakai could be used as an anti-inflammatory cosmeceutical material to alleviate atopic dermatitis.

본 연구에서는 참당귀(Angelica gigas Nakai)의 핵심 유효 성분인 decursin과 decursinol angelate를 높은 수율로 추출한 초임계 이산화탄소 선택 추출물의 항염증 효능을 에탄올 추출물과 비교하여 측정하였다. 항염증 효능을 측정하기 위해 염증 매개 인자인 nitric oxide(NO), 염증성 사이토카인인 interleukin(IL)-6, IL-8 생성량을 측정하였다. NO 생성량은 lipopolysaccharide(LPS)로 염증 반응을 유도한 Raw 264.7 세포를 대상으로 Griess assay를 통해 측정하였고, IL-6 및 IL-8 생성량은 tumor necrosis factor(TNF)-α로 염증 반응을 유도한 human keratinocyte cell line(HaCaT) 세포를 대상으로 enzyme-linked immunoadsorbent assay(ELISA)를 통해 측정하였다. NO 생성량은 초임계 이산화탄소 추출물이 에탄올 추출물에 비해 뛰어나게 억제하였다. IL-6 및 IL-8 생성량 또한 에탄올 추출물은 오히려 증가시키는 반면, 초임계 이산화탄소 추출물은 6.25 ㎍/mL의 농도에서 통계적으로 유의하게 억제하였다(P<0.01). 우리는 이러한 결과를 통해 참당귀 초임계 이산화탄소 선택 추출물이 아토피 피부염을 완화시키는 항염증 코스메슈티컬 소재로써 활용 가능함을 확인하였다.
