采用GC（RI）和GC/MS法对山苍子根、茎、叶、花蕾、花和果实等不同部位的挥发油成分进行了研究。结果表明，不同的油之间的组成有很大的差异。根和果实、茎、叶和阿拉巴斯特拉以及花的油中的主要成分分别是柠檬醛B（橙花醛）、β-水芹烯和β-萜品烯。结果表明，供试菌株均对甘草挥发油敏感，其抑菌圈（DD）和最低抑菌浓度（MIC）均为100 μ g/ml。山苍子的含量范围分别为10.1-35.0 μ g/ml和100-1000 μ g/ml。因此，各部分的油显示出对测试细菌的中等活性。结果表明，L.山苍子属植物中含有大量的挥发油，是一种潜在的药用资源。
The composition of the essential oils obtained by hydrodistillation of different parts of Litsea cubeba, including roots, stems, leaves, alabastra (flower buds), flowers, and fruits, were investigated by GC (RI) and GC/MS. The antimicrobial activity of the oils was assessed with disc diffusion and microbroth dilution assays. The results showed large variations in the composition among the different oils. The major components in the oils from roots and fruits, from stems, leaves, and alabastra, and from flowers were citral B (neral), beta-phellandrene, and beta-terpinene, respectively. The inhibition zone (DD) and MIC values for the bacterial strains tested, which were all sensitive to the essential oil of L. cubeba, were in the range of 10.1-35.0 mm and 100-1000 mu g/ml, respectively. Hence, the oils of the various parts showed moderate activity against the tested bacteria. This investigation showed that the antibacterial activity of L. cubeba was attributed to the essential oils, thus they can be a potential medicinal resource.
