Two novel antioxidants, obtusilactone A (1) and (-)-sesamin (2) have been identified in Cinnamomum kotoense Kanehira. Both showed effective 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity compared with vitamin C, and reducing power compared with BHA. These results suggest that these constituents of C. kotoense act as natural antioxidants and play a potential role in cancer prevention.
在台东肉桂中鉴定出两种新型抗氧化剂，钝叶内酯A（1）和（-）-芝麻素（2）。与维生素C相比，二者均表现出有效的1,1-二苯基-2-苦基肼基（DPPH）自由基清除活性，与丁基羟基茴香醚（BHA）相比具有还原能力。这些结果表明，台东肉桂的这些成分可作为天然抗氧化剂，并在癌症预防中发挥潜在作用。
