염증이란 무엇인가? | 최근에는 혈관질환의 발생 원인으로 혈관 내에서의 염증반응에 대한 관심이 증가되고 있다. 염증은 조직의 손상을 비롯한 외부로부터의 자극 등 다양한 감염원에 대한 체내 반응 중 하나로서(2,3) 국소혈관과 다양한 면역세포가 유기적인 상호작용을 하게 된다. 이 과정에서 대식세포와 같은 염증세포들이 활성화되면서 prostaglandin E2(PGE2), tumor necrosis factorα(TNF-α), interleukin-1β(IL-1β) 등 다량의 염증 매개 인자를 분비하게 된다(4). | |
녹차씨가 함유한 생리적 활성 물질은 무엇이 있는가? | 녹차의 flavone-3-ol을 기본으로 하는 catechins으로서 (+)-catechin, (-)-epigallºCatechingallate(EGCG), (-)-epigallºCatechin(EGC), (-)-epicatechingallate(ECG), (-)-epicatechin(EC)가 함유되어 있는 것으로 알려져 있다(4). 한잔의 녹차에는 150~200 mg의 EGCG가 포함되어 있으며(15) 녹차씨에는 생리적 활성 물질인 사포닌, 플라보노이드류, 비타민과 올레인산 등을 풍부하게 함유하고 있어(15-18) 항염증및 항산화 활성을 가질 것으로 기대된다. 그러나 녹차씨 껍질에 관한 연구는 거의 없는 실정이다. | |
