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.
本研究分析了黄肉楠的叶和嫩枝中的水蒸馏精油，以确定其成分和产量。叶油和嫩枝油中分别鉴定出71种和40种化合物。叶油的主要成分是柠檬烯（18.5%）、百里香酚（10.1%）、对伞花烃（9.6%）、β-石竹烯（8.9%）和香芹酚（8.2%）。嫩枝油的主要成分是β-水芹烯（43.7%）和反式-β-罗勒烯（10.4%）。结果表明，叶油具有优异的抗氧化和抗菌活性，优于嫩枝油。
