title: Composition and antimicrobial activity of the leaf essential oil of Litsea kostermansii from Taiwan.
abstract: The hydrodistillated leaf essential oil of Litsea kostermansii was analyzed to determine its composition and yield. Seventy-three compounds were identified, the main components being beta-eudesmol (22.5%), gamma-eudesmol (18.6%), delta-selinene (8.5%), alpha-eudesmol (6.0%), and gamma-muurolene (4.7%). Oxygenated sesquiterpenes (66.2%) and sesquiterpene hydrocarbons (32.8%) were the predominant groups of compounds. The leaf oil exhibited excellent antimicrobial activities.
