Extraction of natural compounds from secondary metabolites of sugi tree would be helpful to expand the utilization of forest products and increase the economic values. Therefore, the purpose of this plan is to evaluate the antibacterial activities of ethanolic extracts from sugi wood, bark and leaf. And active extract is further separated into several fractions. Active fractions undergo further testing to help isolate and identify antibacterial compounds. Through this research, it is expected to expand the utilization of ethanolic extracts from sugi tree and increase the economic values of sugi plantations.柳杉抽出物抗細菌活性Cryptomeria japonicaExtractAntibacterial activity
