The essential oils of the bark of young branches of Cinnamomum loureirii Nees. from China were isolated by hydrodistillation (HD) and microwave-assisted hydrodistillation (MHD) in yields of 5.8% and 6.1%, respectively. The chemical composition of the oils was examined by GC and GC/MS. Twenty components in the HD oil and 21 components in the MHD oil were identifed, representing 95.2% and 94.5% of the related oils, respectively. Major components in the HD and MHD oils were cinnamaldehyde (62.6%, 69.6%), α-copaene (16.0%, 5.4%) and β-cadinene (7.7%, 4.7%).
