[국내논문]문주란의 항염효과와 화장료적 특성 Anti-inflammatory Activity of Crinum asiaticum Linne var. Japonicum Extract and its Application as a Cosmeceutical Ingredient원문보기
문주란(Crinum asiaticum Linne var. japonicum)은 한국, 말레이지아 등 동남아시아 지역에서 관절통, 해열, 궤양 치료, 국부의 소염 및 해열 등의 목적에 민간요법 등으로 오래 전부터 사용되어 오고 있다. 본 연구에서는 이러한 문주란의 화장료 조성물로서의 가능성을 확인하기 위하여 iNOS (inducible nitric oxide synthase) 억제 그리고 PGE2, IL-6, and IL-8 방출 억제에 의한 항염 효능을 측정하였다. pH를 3.5로 조절하고 95% ethanol을 사용하여 추출한 후, HPLC 실험으로 문주란의 주성분이 면역조절물질로 잘 알려진 lycorine이며 대략 1% 정도 함유한 것을 확인하였고 그 함량은 문주란의 추출 부위 및 추출방법에 따라 달랐다. 리포다당(lipopolysaccharide, LPS)에 의해 활성화된 생쥐 대식세포(RAW 264.7 cells)에서 생성되는 NO 형성의 억제능을 측정한 항염실험에서, 문주란 에탄을 추출물은 투여량에 비례하는 저해능을 가지고 있음을 확인할 수 있었다($IC_{50} = 83.5 {\mu}g/mL$). 또한 RT-PCR법을 이용하여 문주란 에탄을 추출물이 iNOS 유전자 발현도 억제함을 확인하였다. 또한, 문주란 추출물은 전혀 세포독성을 보이지 않았으며 오히려 LPS에 대하여 세포증식효과를 나타내었다(세포생존율 약 $10{\sim}60%$ 증가). 인간의 섬유아세포에서 과산화수소에 의해 활성화된 PGE2, IL-6 및 IL-8 방출 억제효능 측정 실험에서는 0.05%와 1% 농도 이상에서 (PGE2와 IL-6의 분비가) 거의 완전히 억제됨을 확인할 수 있었고, 나아가서 IL-8의 경우는 모든 실험농도 범위에서 완전히 억제되었다(>0.0025%). 이러한 결과로부터 문주란의 추출물이 충분한 항염 효과를 가지고 있음을 확인할 수 있었다.

Crinum asiaticum Linne var. japonicum has long been used as a rheumatic remedy, an anti-pyretic, an anti-ulcer treatment, and for the alleviation of local pain and fever in Korea and Malaysia. In order to investigate the possibility of Crinum asiaticum Linne var. japonicum extract as a cosmetic ingredient, we measured its anti-inflammatory effect by inhibition of iNOS (inducible nitric oxide synthase), and the release of PGE2, IL-6, and IL-8. HPLC experiment after extraction with 95% ethanol at pH 3.5 showed that Crinum asiaticum Linne var. japonicum was mainly composed of lycorine (up to 1%), a well-known immunosuppressant. The content of lycorine varied depending on the type of tissue analyzed and the extraction method. In anti-inflammatory assay for inhibition of nitric oxide formation on lipopolysaccharide (LPS)- activated mouse macrophage RAW 264.7 cells, the ethanolic extract of Crinum asiaticum showed inhibitory activity of NO production in dose-dependent manner ($IC_{50} = 83.5 {\mu}g/mL$). Additional study by RT-PCR demonstrated that the extract of Crinum asiaticum significantly suppressed the expression of the iNOS gene. Moreover, the extract of Crinum asiaticum did not show my cytotoxicity, but did show cell proliferation effect against LPS ($10{\sim}60%$ increase of tell viability). In an assay to determine inhibition of the $H_2O_2$-activated release of PGE2, IL-6, and IL-8 in human normal fibroblast cell lines, the release of PGE2 and IL-6 was almost completely inhibited above concentrations of 0.05% and 1%, respectively. Moreover, the release of IL-8 was completely inhibited over the entire range of concentrations (> 0.0025%). The result showed that the extract of Crinum asiaticum Linne var. japonicum has sufficient anti-inflammatory effect. There-fore, Crinum asiaticum Linne var. japonicum extract may be useful as an ingredient of cosmetic products.
