초록

본 실험은 동백꽃의 효능을 알아보기 위하여, 동백꽃을 에틸알콜로써 추출한 후 극성이 다른 다양한 유기용매로 분획하여 나온 fraction으로 신생혈관생성 억제, cell cytotoxity, 세포부착분자에 대한 기능을 ELISA, westen blot 등으로 조사하였다. 신생혈관생성 억제 효과는 특히butanol 층에서 70.2%로 가장 높았으며, acetone층이 54.2%, 그리고 ethylacetate층이 37.0%, chloroform층이 21.2%로 유의성 있는 억제효과가 있었다. 특히 동백꽃의 butanol층은 신생혈관생성억제제로서 좋은 효과가 있는 것으로 판단된다. 그리고, 추출물의 농도별로 cell cytotoxity를 조사한 결과 농도가 200 ug/ml 이하에서 세포독성은 나타나지 않았다. Cell adhesion 저해율은 추출물의 농도 200 μg/mL 에서 ICAM-1은 52.9%, VCAM-1은 62.5%, 그리고 E-selectin은 35.7%로 나타났으며 동백꽃의 추출물의 성분 증가에 따라 발현이 감소됨으로써 cell adhesion을 저해하는 것으로 확인되었다. Westen blot 에서 첨가한 동백꽃 추출물의 농도가 높아질수록 신호전달분자의 발현이 약해지는 것을 관찰할 수 있었다. 따라서 신호전달 분자는 동백꽃 추출물에 의해서 신호전달이 차단되며, NF-KB를 억제함으로서 신생혈관생성을 저해하는 것으로 확인되었다. 따라서 동백꽃 추출물은 항암제 및 항비만제제로서 유용할 것으로 판단된다.

The Camella japonica flower(CJF) extract was studied for their anti-angiogenenic and anti-cell adhesion effect. CJF-extract inhibited the tube formation on human umbilical vein endotherial cells(HUVEC) with butanol extract by 70.2%, acetone extract by 54.2%, ethyl acetate extract by 37.0%, chloroform extract by 21.2%. Cell adhesion molecules were effectively suppressed at different concentration of CJF at 50, 100, 200 ug/well such as for intercellular adhesion molecule(ICAM) by 5.9%, 29.4% and 52.9%, for vascular cell adhesion molecule(VCAM) by 12.5%, 43.8% and 62.5%, for E-selectin by 7.1%, 21.4% and 35.7%, respectively. Signal molecules of vascular endotherial growth factor receptor 2(VEGFR2), ${/beta}$-catenin and PI3K are inhibited by different concentration of CJF at 10, 20 and 30 ${\mu}g/mL$ with western blot. Angiogenesis will be inhibited with suppressing NF-kB molecule resulted in signal molecules blocked by CJF. CJF will be useful materials for treatment of angiogenesis related diseases such as cancer, metastasis, rheumathioid arthritis and obesity.
