Abstract

Red rose petals are usually disposed but they are an abundant source of phenolics and traditionally used as food supplement and as herbal medicine. Of the Various phenolics, they are known to have anticancer, antioxidant, and anti-inflammatory properties. In this study, we investigated the anti-inflammatory effects of red rose ethanolic extracts(GRP) on lipopolysaccharide (LPS)-activated RAW 264.7 cells. The results demonstrated that pretreatment of GRP(500㎍/mL) significantly reduced NO production by suppressing iNOS protein expression in LPS-stimulated cells. Anti-inflammatory effects byred rose petal were observed in the following. Red rose petal inhibited the translocation of NF-κB from the cytosol to the nucleus via the suppression of IκB-α phosphorylation and also inhibited LPS-stimulated NF-κB transcriptional activity. These findings suggest that red rose petal exert anti-inflammatory actions and help to elucidate the mechanisms underlying the potential therapeutic values of red rose petal. Therefore, red rose petal could be regarded as a potential source of natural anti-inflammatory agents.

붉은 장미꽃잎 에탄올 추출물은 효과가 풍부한 페놀 성분의 공급원이며 전통적으로 식품 보충제 및 약초로 사용되고 있다. 또한 다양한 식물페놀 성분은 항암, 항산화 및 항염증 특성을 갖는 것으로 알려져 있다. 따라서 본 연구에서는 붉은 장미꽃잎 에탄올추출물(GRP) 유래 활성 분획물 분석 및 lipopolysaccharide(LPS)로 유도된 마우스 대식세포주인 RAW264.7 세포와 마우스 폐포 대식세포주인 MH-S 세포에서 붉은 장미꽃잎 에탄올추출물의 항염증 활성 효과를 조사하였다. 그 결과 GRP(500 ㎍/mL)의 전처리 LPS 자극 세포에서 iNOS 단백질 및 염증성 싸이토카인 mRNA 발현을 크게 억제하였다. 빨간 장미꽃잎 에탄올 추출물에 의한 항균활성 효과는 다음과 같이 관찰되었다. 붉은 장미꽃잎은 IκB-α 인산화의 억제를 통해 시토졸에서 핵으로의 NF-κB의 전좌를 억제하고 또한 LPS로 자극된 NF-κB 전사 활성을 억제 하였다. 이러한 연구 결과는 빨간 장미꽃잎 에탄올 추출물이 항염증 작용을 발휘 하고 빨간 장미꽃잎의 잠재적인 치료 가치성 및 기본 메커니즘을 규명 할 수 있었다. 결론적으로 붉은 장미꽃잎 에탄올 추출물이 다양한 활성 성분 함유 및 천연 항염증제의 잠재적 공급원으로 활용 가능성이 있음을 시사 하였다.
