水蒸气蒸馏法提取肉桂的花、嫩叶和枝的精油。采用气相色谱-火焰离子化检测器（GC/FID）和气相色谱-质谱（GC/MS）对冰片进行了比较研究。在所鉴定的挥发油成分中，氧化萜类成分含量最高（花50.83%，叶70.75%，枝78.22%）。d-冰片是C.黄毛藓冰片含量最高（花12.13 ± 0.67 g/kg，叶17.22 ± 0.85 g/kg，枝4.47 ± 0.79 g/kg），樟脑在花中含量低，叶中含量低（0.05 ± 0.01 g/kg），枝中含量高（1.09 ± 0.44 g/kg）。这些结果表明，香樟叶和花的挥发油成分中含有较多的挥发性成分。黄毛藓冰片是一种较好的制备d-萜类化合物的资源，在生长时间延长的过程中可能存在α-蒎烯-樟脑-萜类化合物的生物转化。黄毛藓冰片（花<叶<分支）
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 alpha-pinene-borneol-camphor bioconversion during the growth time extension of C. camphora chvar. Borneol (flower < leaf < branch)
