In addition, we will continue to collect other geographical provenances of indigenous cinnamon, It is expected to find different chemotypes from these endemic tree species. Through this study, it is expected that antioxidant compounds isolated from C. osmophloeum be of great potential as medicines for disease control or as raw materials for synthesizing useful analogues in industry.土肉桂不同化學品系葉子精油抗氧化活性氣相層析質譜儀Cinnamomum osmophloeumDifferent chemotypesLeafEssential oilAntioxidant activitiesGC-MS
