摘要

為了降低超氧自由基、氫氧自由基、單峰氧以及過氧化氫等活性氧對生物的危害，有關自由基與抗氧化等相關研究，已成為當前生物醫學之熱門研究主題。然而，國內本土樹種抽出物在這一方面應用之可行性，一直缺乏深入的研究，故本文將針對氧的危害、細胞中活性氧的形成與抗氧化之防禦以及本土樹種之抗氧化潛能等主題，作一綜合性整理與介紹。

To decrease the intracellular oxidative stresses which are caused by reactive oxygen species (ROS) including superoxide radicals, hydroxyl radicals, singlet oxygen, and hydrogen peroxide, the topic of free radical and antioxidant is broadly discussed in the biologic and medical fields to date. However, the extracts from indigenous plants in Taiwan have rarely been applied on antioxidant in the literature. In this article, therefore, oxygen toxicity, the sources of intracellular ROS, and the intracellular antioxidant defenses as well as the potential antioxidant activity of extracts from indigenous wood in Taiwan are addressed.
