This study was conducted to investigate the antioxidant compounds and activities of Prunus yedoensis Matsumura bark (PYMB) ethanol extracts (EE) and various other fractions. Among them, the highest total phenol content was 496.80 mg gallic acid equivalent/g in the ethyl acetate fractions (EAF). The ...

유리라디칼이 체내 과잉생산될 경우 어떠한 문제가 발생되는가? | 여러 질환 발병의 원인으로 알려진 유리라디칼(free radical)은 체내 정상적인 대사과정 중 생성되는 reactive nitrogen species (RNS), reactive oxygen species (ROS) 등을 말한다. 이들이 체내 과잉생산 될 경우 DNA, 단백질 및 세포의 산화적 손상을 가져오고 알츠하이머병, 암, 심혈관질환 등을 일으킨다. 체내에는 산화적 스트레스에 대한 방어시스템이 존재하고 있지만 환경오염, 과도한 스트레스, 화학약품, 음주, 흡연 등에 의해 유리라디칼의 생성이 더 많아지고 있어 체내 산화 방어시스템을 증가시킬 수 있는 항산화제에 대한 개발의 필요성이 강조되고 있다(Hyon 등, 2010; Kim 등 2016; Valko 등, 2007; Wojsiat 등 2018). | |
왕벚나무의 열매는 어떻게 이용되는가? | 왕벚나무(Prunus yedoensis Matsumura)는 장미과 벚나무속에 속하며 우리나라에는 20여종이 분포하고 있다. 왕벚나무의 열매는 치통, 유선염, 수종, 각기병 및 통경제로 이용되었으며(Kim 등, 1998), 왕벚나무의 껍질(화피, 樺皮)은 우육체, 기침, 두드러기 등의 민간약으로 사용되어왔다(Park 등, 1998). 왕벚나무 껍질은 임상에서 염증성 질환에 주로 이용되고 있으며, 최근 사용량이 증가하는 추세이다(Hong 등, 2013). | |
