In this study, we report the preliminary data on the chemical composition of Yemeni Schinus molle L. volatile oil obtained by supercritical extraction with carbon dioxide (40°C and 90 bar), SFE, and by hydrodistillation (HD). The composition of the volatile oil has been analysed by GC and GC-MS. The content of the major constituents in the oils from leaves varied in the following ranges: germacrene D 3.7% in SFE and 16.7% in HD; β-caryophyllene 19.1% in SFE and 13.5% in HD. The amount of monoterpenes constituted 4%, in all the analysed samples, while the number of sesquiterpenes was 44% in supercritical and 67% in HD oil. Some compounds were not identified by GC-MS and it will require further analysis using other analytical techniques.
在这项研究中，我们报告了用超临界二氧化碳（40°C 和 90 巴）、SFE 和水蒸馏（HD）提取的也门麻疯树挥发油的化学成分的初步数据。用 GC 和 GC-MS 分析了挥发油的成分。叶油中主要成分的含量在以下范围内变化：SFE 中的反式-杜松烯 D 为 3.7%，HD 中的为 16.7%；SFE 中的β-石竹烯为 19.1%，HD 中的为 13.5%。所有分析样品中的单萜含量为 4%，而 SFE 中的倍半萜含量为 44%，HD 中的为 67%。一些化合物无法通过 GC-MS 鉴定，需要进一步使用其他分析技术进行分析。
