Byproducts from this tree species, such as essential oils, tea and wine, are quite popular. Our previous researches have showed that essential oils from leaves of this tree species show excellent uric-acid reduction, anti-inflammatory, and anti-tumor activities. The abilities to reduce blood sugar and lipid were also reported to be excellent. It was reported that plants irradiated with UV-B would accumulate secondary metabolites. However, the application of this technique to C. osmophloeum is limited. The purpose of this study is to optimize the process of UV-B irradiation to C. osmophloeum, and correlates this process to the accumulation of bioactive compounds in C. osmophloeum. We envision promoting the health benefits and the economic values of this tree species.土肉桂抽出物葉子紫外光Cinnamomum osmophloeumExtractivesLeafUltraviolet light
