山苍子Litsea cubeba（Lour.）是一种很有前途的经济作物，果实富含精油。本文报道了丁香挥发油的化学成分。测定了我国8个地区的山苍子果实的EOLC。通过水蒸馏和气相色谱-质谱（GC-MS）分析得到的总精油含量为3.04%至4.56%。共鉴定出59种化合物，以单萜类化合物为主（94.4-98.4%），以橙花醛和香叶醛为主（78.7-87.4%）。出乎意料的是，D-柠檬烯在水果中的含量较少（0.7-5.3%），这与以前的报道（6.0-14.6%）不同。几种组分仅在某些区域检测到，并且化合物如邻异丙基甲苯和艾瑞莫芬以前从未在EOLC中报道过。这些结果表明，EOLC的化学成分的显着区域差异。本研究为该菌的生物活性、育种工作和工业应用提供了重要信息。古巴。
Litsea cubeba (Lour.) Pers. is a promising industrial crop with fruits rich in essential oils. The chemical composition of essential oils of L. cubeba (EOLC) were determined for fruits harvested from eight regions in China. The overall essential oil content, obtained by hydrodistillation and analyzed by gas chromatography–mass spectrometry (GC-MS), ranged from 3.04% to 4.56%. In total, 59 compounds were identified, the dominant components being monoterpenes (94.4–98.4%), represented mainly by neral and geranial (78.7–87.4%). D-limonene was unexpectedly a lesser constituent (0.7–5.3%) in fruits, which differed from previous reports (6.0–14.6%). Several components were only detected in certain regions and compounds such as o-cymene and eremophilene have never before been reported in EOLC. These results demonstrate significant regional variation in the chemical composition of EOLC. This investigation provides important information with regard to the bioactivity, breeding work and industrial applications of L. cubeba.
