The essential oils from bark and leaves of Cedrelopsis grevei Baill (Ptaeroxylaceae), an aromatic and medicinal plant from Madagascar, are widely used in folk medicine. These two commercially available oils have been examined separately by means of GC-MS. The oil constituents were identified according to their mass spectra and their relative retention indices determined on both polar and non-polar stationary phase capillary columns. A total of 55 compounds have been identified constituting 76.7% (bark) and 91.6% (leaves) of the volatile constituents. Both oils were found to have a similar composition; however the relative percentages of some compounds notably differed. The bark essential oil contained beta-pinene (17.1%), cis-sesquisabinene hydrate (12.8%) and caryophyllene oxide (7.0%) as the main components whereas the leaf essential oil was largely dominated by trans-beta-farnesene (35.6%); beta-pinene (12.8%), cis-sesquisabinene hydrate (9.8%) and ar-curcumene (8.6%) were also present as major components. As far as we know, this is the first report on the Cedrelopsis grevei bark and leaf essential oils which therapeutic properties may be attractive for aromatherapy.
格氏土檀香（土檀香科）是一种来自马达加斯加的芳香药用植物，其树皮和树叶的精油在民间医学中广泛使用。已通过气相色谱 - 质谱联用仪（GC - MS）分别对这两种市售精油进行了检测。根据其质谱图以及在极性和非极性固定相毛细管柱上测定的相对保留指数来鉴定油中的成分。总共鉴定出55种化合物，它们分别占挥发性成分的76.7%（树皮）和91.6%（树叶）。发现两种精油的成分相似；然而，某些化合物的相对百分比明显不同。树皮精油的主要成分包含β-蒎烯（17.1%）、顺式倍半水芹烯（12.8%）和氧化石竹烯（7.0%），而叶精油主要以反式β-法呢烯（35.6%）为主；β-蒎烯（12.8%）、顺式倍半水芹烯（9.8%）和芳姜黄烯（8.6%）也是主要成分。据我们所知，这是关于格氏土檀香树皮和树叶精油的首次报道，其治疗特性可能对芳香疗法具有吸引力。
