초록

Persicaria orientalis (L.) Spach (Po)와 Potentilla fragarioidesvar. major Maxim (Pf)의 추출물로 reactive oxygen species(ROS)와 같은 free radical의 억제를 통한 항염증 활성을 살펴보았다. 또한, Po와 Pf로 LPS를 처리한 murine macrophageRAW 264.7 세포에서 발생한 nitric oxide의 저해와 NF-κB의핵으로 translocation의 저해를 살펴보았다. 3-morpholinosydnoniminehydrochloride (SIN-1) 50 μM에 의해 유도된 ROS의 Po에 의한 50% 저해값 (IC50)은 23.35±1.27 mg/mL, Pf에 의한 IC50은8.46±1.22 mg/mL이었다. 또한, SIN-1 50 μM에 의해 유도된peroxynitrite의 Po에 의한 IC50은 2.19±0.04 mg/mL, Pf에 의한IC50은 0.80±0.02 mg/mL이었다. LPS 1 mg/mL을 처리한 RAW264.7 세포에서 Nitric oxide는 증가하였으나 Po와 Pf 추출물을 처리한 그룹에서 농도의존적, 유의적으로 감소하였다. Po추출물을 처리한 그룹의 Nitric oxide 생성량은 13.34±0.67 μM,Pf 추출물을 처리한 그룹의 Nitric oxide 생성량은 11.45±0.57μM이었다. 또한, Po와 Pf 추출물은 LPS를 처리한 RAW 264.7세포에서 NF-κB의 핵으로의 translocation을 저해하였다. 그러므로, Po와 Pf는 항염증 소재로서의 가능성이 충분하다고 사료된다.

Persicaria orientalis (L.) Spach (Po) and Potentillafragarioides var. major Maxim (Pf) extracts were analyzed toinvestigate anti-inflammation through their suppressing effects onfree radicals such as reactive oxygen species (ROS). In addition,with regard to Po and Pf, an analysis was conducted of theirinhibitory effect on nitric oxide, which is produced in lipopolysaccharide(LPS)-treated murine macrophage RAW 264.7 cells,and their inhibitory effect on the translocation of the nucleus ofnuclear factor-kappa B (NF-κB). The IC50 value of ROS, whichwas induced by 50 μM 3-morpholinosydnonimine hydrochloride(SIN-1), was found to be 23.35±1.27 μg/mL due to the effect ofthe Po extract, and 8.46±1.22 μg/mL due to the effect of the Pfextract. In addition, the IC50 value of peroxynitrite treated with thePo extract was 2.19±0.04 μg/mL, whereas that of peroxynitritetreated with the Pf extract was 0.80±0.02 μg/mL. ROS andperoxynitrite were induced by 50 μM 3-morpholinosydnoniminehydrochloride. There was an increase in the amount of nitric oxidein the RAW 264.7 cells treated with LPS (1 μg/mL), whereas thelevel of NO was observed to significantly and dose-dependentlydecrease in the cells treated with Po and Pf. The amount of nitricoxide produced by the group treated with 10 μg/mL of the Pfextract was 11.45±0.57 μM. Furthermore, the Po extracts inhibitedthe translocation of the nucleus of NF-κB in LPS-treated RAW264.7 cells. Therefore, it is highly possible that Po and Pf haveanti-inflammatory properties.
