Abstract

The purpose of this study was to investigate the role of the Vaccinum oldhami fruit extract as a cosmetic additive. As a result of having macrophage (RAW 264.7) measured a cell toxicity effects of 70% ethanol extract from Vaccinum oldhami fruit, it shown 118% with toxicity at $500{\mu}g/ml$ concentration. In nitric oxide synthesis inhibition effect, 70% ethanol extracts from Vaccinum oldhami fruit shown 47.3% at $1,000{\mu}g/ml$ concentration. The iNOS, COX-2 protein expression inhibitory effect by western blot of 70% ethanol extract from Vaccinum oldhami fruit was decreased by 36.13%, 29.61% at $500{\mu}g/ml$ concentration. And iNOS, COX-2 mRNA expression inhibitory effect by reverse-transcription-PCR of 70% ethanol extract from Vaccinum oldhami fruit was decreased by 62.25%, 90.07% at $500{\mu}g/ml$ concentration. All these finding that extract from Vaccinum oldhami fruit could prove that their have effects anti-inflammatory efficacy. And extract from Vaccinum oldhami fruit has potential as a cosmetic ingredients.

본 연구는 천연물 소재인 정금나무 열매(Vaccinum oldhami fruit) 에탄올 추출물을 이용하여 항염증 효과에 대하여 검증하였다. 대식세포인 RAW 264.7 세포를 이용하여 정금나무 열매 추출물로 처리했을 때 세포 생존율을 확인한 결과 $500{\mu}g/ml$ 농도에서 118%를 나타내었다. 대식세포를 이용하여 정금나무 열매 추출물의 농도가 증가함에 따라서 변화하는 NO 생성량을 측정한 결과 최고농도 $1,000{\mu}g/ml$에서 47.3%로 감소한 것을 확인할 수 있었다. 정금나무 열매 에탄올 추출물을 Western blot을 이용하여 단백질 발현을 측정한 결과 처리한 세포군에서 농도가 증가함에 따라 iNOS와 COX-2의 단백질 발현양이 감소하여 최고 농도인 $500{\mu}g/ml$에서 각각 36.13%, 29.61%의 발현 억제를 보여주었다. Reverse-transcription PCR을 통하여 mRNA 발현양을 측정한 결과 iNOS와 COX-2의 mRNA 발현양이 감소하여 $500{\mu}g/ml$ 농도에서 62.25%, 90.07%로 내었다. 이러한 결과로 보아 정금나무 열매 에탄올 추출물의 항염증에 관한 그 효능을 확인할 수 있었고, 따라서 정금나무 열매 추출물을 이용한 천연 항염증 화장품 소재개발 이용 가능성을 넓힐 수 있을 것으로 사료된다.
