Abstract
Cinnamomum kanehirae Hayata is an endemic tree species in Taiwan. Leaf essential oils from 26 sources of C. kanehirae were obtained by hydrodistillation and their chemical constituents were analyzed by gas chromatography-mass spectrometry (GC-MS). Fifty-eight compounds were identified from C. kanehirae leaf essential oils. The main constituents in leaf essential oils were linalool, 1,8-cineole, β-selinene, 1-hexadecyne, and -cadinol. According to the chemical compositions of leaf essential oils and their relative contents obtained from GC-MS analyses, cluster analysis, and principal component analysis, the 26 sources examined were classified into five chemotypes: linalool type, linalool/1,8-cineole type, 1,8-cineole type, linalool/-cadinol type, and mixed type. The biochemical correlations between the major constituents of C. kanehirae were examined and their relationship is discussed.
