title: Composition, antioxidant and antimicrobial activities of leaf and twig essential oils of Litsea akoensis from Taiwan.
abstract: This study analyzed the hydrodistilled essential oils in the leaves and twigs of Litsea akoensis to determine composition and yield. Seventy-one and 40 compounds were identified in the leaf and twig oils, respectively. The main components of leaf oil were limonene (18.5%), thymol (10.1%), p-cymene (9.6%), beta-caryophyllene (8.9%), and carvacrol (8.2%). The main components of twig oil were beta-phellandrene (43.7%) and trans-beta-ocimene (10.4%). The results demonstrated that leaf oil had excellent antioxidant and antimicrobial activities, superior to those of twig oil.
