Our study investigated the fibrinolytic, thrombin inhibitory, anti-oxidative and anti-inflammatory activities of the water extract and solvent fractions isolated from Pleurotus ferulea. Fibrinolytic activity was investigated using the fibrin plate method. Thrombin inhibitory activity was used to analyze thrombin inhibitor assay. The DPPH assay was used to estimate anti-oxidative activity. Inhibition of NO production was measured for anti-inflammatory activity in LPS-activated murine RAW 264.7 macrophage cells. An MTS assay was used to evaluate the effects of the water extract and solvent fractions isolated from Pleurotus ferulea on cell viability. Our results showed the fibrinolytic activity to be strong in the ethyl acetate fraction at 1.33 plasmin units. The ethyl acetate fraction also showed high thrombin inhibitory activity at 94.45%. The anti-oxidative activity of the water extract was 37.01% and the anti-inflammatory activity of the chloroform fraction was 98.13%. These findings suggest that Pleurotus ferulea's extract and fractions could be applicable in the development of functional foods for the treatment and prevention of cardiovascular diseases.

본 연구는 국내 생약중 도라지를 포함, 인삼, 당귀, 생강, 마 5가지를 선별하여 각 원물별로 항산화 활성 가장 높은 기준으로 증숙시킨 조건의 흑도라지, 흑삼, 흑당귀, 흑생강, 흑마를 확보하였다. 증숙시킨 5가지 생약은 다시 혼합 추출(BMHE; Black Mixed Herbal Extract)하여 증숙하지 않은 생약 혼합 추출물(MHE; Mixed Herbal extract)과 항산화, 항염 및 항알러지 활성을 비교하여 증숙공정이 생약의 생리활성에 미치는 긍정적인 영향을 바탕으로 피부향장 소재로 활용가능성을 확인하고자 연구하였다. 실험은 MHE와 BMHE를 각각 50% Ethyl alcohol로 추출하여 감압농축하여 생리활성을 평가하였으며, MHE와 BMHE 추출물에 대한 세포생존률을 확인한 결과 $1,000{\mu}g/ml$의 농도에서 각각 89.4%와 95.3%의 세포생존률을 보임에 따라 $1,000{\mu}g/ml$ 이하의 농도에서 HME와 BMHE 모두 세포독성이 거의 적은 것을 확인하였다. DPPH radical scavenging effects 항산화 활성에 대하여 MHE와 BMHE을 비교한 결과 농도 의존적으로 항산화 활성을 보였으며 $1,000{\mu}g/ml$의 농도에서는 각각 66.8%와 74.2%의 라디칼 소거능을 확인하였다. NO assay로부터 항염활성을 비교한 결과에서도 MHE와 BMHE 모두 농도 의존적으로 NO의 함량 감소시켰으며 $1,000{\mu}g/ml$로 처리한 농도에서는 59.5%와 64.7%의 억제율을 각각 보임에 따라 항염 효과도 우수한 것을 확인하였다. 항알레르기 효능 실험 중 하나인 5-LO 억제효능을 측정하여 ME와 BME의 항알러지 효능을 측정한 결과 상기의 결과와 마찬가지로 농도 의존적으로 5-Lipoxygenase를 억제하였으며, $1,000{\mu}g/ml$의 농도로 MHE와 BMHE를 처리하였을 시 5-Lipoxygenase 효소활성에 대하여 각각 76.2%와 83.5%의 높은 억제율을 확인 하였다. 이는 양성대조군인 EGCG를 $200{\mu}g/ml$의 농도로 처리한 9.10%에 근접한 억제율을 보임에 따라 항알러지 효과가 우수한을 확인할 수 있었다. 실험 결과를 바탕으로 BMHE가 MHE보다 항산화, 항염, 항알러지 활성이 우수한 것을 확인 할 수 있었으며, 이는 증숙기법이 생약의 생리활성을 높여주는 것은 물론 더 나아가 본 연구를 통해 확보된 5가지 흑도라지, 흑삼, 흑당귀, 흑생강, 흑마는 향후 피부향장 소재로 활용이 용이할 것으로 사료된다.

Anti-inflammatory and anti-oxidative activities were examined on the extract of Dendranthema indicum (D. indicum) flowers. The flowers were extracted two times for 24 h each with 70% ethanol. Upon the biological activities screening, the ethanol extract exhibited potent free radical scavenging activities and inhibited the production of nitric oxide on LPS-induced RAW264.7 macrophages effectively without causing cell toxicity. Further purification by medium pressure liquid hromatography (MPLC) and identification of the isolates led to identification of cynaroside (1) and apigetrin (2). The chemical structures of the isolated compounds were elucidated based on spectroscopic data including nuclear magnetic resonance (NMR) spectra, as well as comparison of the data to the literature values. Also, the quantitative analysis of the compounds was perfromed by high-performance liquid chromatography (HPLC). The isolates 1 and 2 were determined to inhibite the nitric oxide (NO) production dose-dependently. Based on these results, it was suggested that D. indicum extract could be useful as anti-inflammatory agents in cosmetics applications.

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.

In this study, we investigated anti-inflammatory and anti-bacterial constituents from Daucus carota var. sativa (carrot) areal parts. For the extract and solvent fractions, the anti-inflammatory activities were examined by measuring the nitric oxide (NO) production using LPS-stimulated RAW 264.7 cells. Among them, the ethyl acetate (EtOAc) fraction decreased the NO level in a dose-dependent manner. To elucidate further anti-inflammatory mechanisms, EtOAc fraction was evaluated by estimating their effects on the production of prostaglandin $E_2$ and pro-inflammatory cytokines as well as on the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). As a result, the EtOAc fraction was determined to inhibit the production of $PGE_2$, IL-$1{\beta}$, IL-6 and reduce the iNOS, COX-2 protein expression. Upon the anti-bacterial tests using Staphylococcus epidermidis and Propionibacterium acnes, n-hexane (Hex) and EtOAc fractions showed the most potent activities. Three phytochemicals were isolated form the EtOAc fraction; diosmetin (1), diosmin (2), cynaroside (3). The chemical structures of the isolated compounds were elucidated based on the spectroscopic data including $^1H$ and $^{13}C$ NMR spectra, as well as comparison of the data to the literatures. Anti-inflammatory and anti-bacterial effects were studied for the isolates. All of the compounds (1 - 3) decreased the NO production, effectively. Also, compound 3 showed anti-bacterial activity on P. acnes. Based on these results, D. carota var. sativa extract could be potentially applicable as anti-inflammatory and anti-bacterial ingredients in cosmetic formulations.
