Abstract

Cinnamomum camphora is an important timber and economic tree species in southern China. The leaves of C. camphora are a renewable biological resource and are an important resource for the comprehensive development and utilization of eucalyptus. The composition and functional characteristics of ethanol extracts from leaves of three chemotypes C. camphora were elucidated by Gas Chromatography/Mass Spectrometer (GC/MS). The results showed that the known contents of volatile organic components (VOCs) detected in the three chemotypes leaves accounted for 98.428%, 45.185% and 97.907% of the total essential oil respectively, and two of them were identified, namely aromatic camphor (Linalool 66.774%) and camphor type (Camphor 47.483%). However, a special component with 53.070% content in the one chemotypes was not identified. Its second-rich component is trans-(+)-Nerolidol, with a content of 17.725%. More substances were detected in Camphor type than those of the other two chemotypes, and there were more VOCs at low distillation points. The unknown chemotypes of C. camphora are more abundant in VOCs than that of distillation points. Meanwhile, some bioactive components including 3-Hexen-1-ol, (Z)-, Eucalyptol, Caryophyllene, Humulene and Caryophyllene oxide were detected in three chemotypes of C. camphora.
