The leaf essential oil of Litsea nakaii was isolated by hydrodistillation and analyzed to determine its composition and yield. Fifty-five compounds were identified, the main components being α-humulene (15.5%), δ-cadinene (9.2%), (E)-β-ocimene (8.1%), and δ-selinene (7.1%). The leaf oil exhibited excellent antimicrobial activities.
