The essential oils obtained by hydrodistillation of flowers, young leaves and epicormic branches of Cinnamomum camphora chvar. Borneol were comparatively studied by gas chromatography with flame ionization detector (GC/FID) and GC/mass spectrometry (GC/MS). Among the verified constituents, oxy-terpene accounted for the most abundant constituent in all volatile oils (flowers 50.83%, leaves 70.75%, branches 78.22%). d-Borneol, the characteristic oxy-terpene of the volatile oils of C. camphora chvar. Borneol, was the highest-content compound among all the three parts (flowers 12.13±0.67 g/kg, leaves 17.22±0.85 g/kg and branches 4.47±0.79 g/kg), while camphor was absent in flowers, low in leaves (0.05±0.01 g/kg) but rich in branches (1.09±0.44 g/kg). These findings suggested that volatile oils from the leaves and flowers of C. camphora chvar. Borneol would serve as a better resource for d-borneol preparation, and there might be an α-pineneâborneolâcamphor bioconversion during the growth time extension of C. camphora chvar. Borneol (flower < leaf < branch)
