The essential oil of the liverwort Plagiochila asplenioides from two different locations in Northern Germany were investigated by chromatographic and spectroscopic methods. Seven compounds were isolated by preparative gas chromatography (GC) and their structures investigated by mass spectrometry (MS), NMR techniques and chemical correlations in combination with enantioselective GC. In addition to known
通过色谱法和光谱法研究了来自德国北部两个不同地点的地衣 Plagiochila asplenioides 的精油。通过制备型气相色谱 (GC) 分离出七种化合物,并通过质谱 (MS)、核磁共振技术和化学相关性结合对映选择性 GC 研究了它们的结构。除了已知成分,aromadendra-1(10),3-diene,两种芳香倍半萜烃,bisabola-1,3,5,7(14)-tetraene 和 bisabola-1,3,5,7-tetraene,三种除 ent-4-epi-maaliol 外,倍半萜醚、muurolan-4,7-peroxide、plagiochilines W 和 X 还首次被鉴定为天然化合物。
