In this study, to understand the charasteristics of its essential oil (EO) hydrodistillation will be used for EO extraction of its leaves collected from various plants. GC-MS and GC-FID will be used to examine variations and contents of chemical composition in EO. Moreover, the absolute configuration of the main constituent and its content of EO will be illustrated by GC-FID with chiral column. In addition, we will also investigate the effects of the extraction time on the yield of EO and the content of main constituents. Furthermore, we plan to assess the anxiolytic activity of EO. We expect that the optimum extraction time and conditions could be found. The results obtained from this study will be helpful to understand the characteristics of leaf essential oil and its constituent from C. osmophloeum ct. linalool and expand its applications, which may increase the economic value of its products.枷羅木醇型土肉桂葉子精油收率氣相層析－質譜分析火焰離子偵測器氣相層析儀絕對立體組態抗焦慮活性Cinnamomum osmophloeum ct. linaloolleafessential oilGC-MSGC-FIDabsolute configurationanxiolytic activity
