Fourteen compounds were isolated from the 95% ethanol reflux extract of Asarum sieboldii Miq. var. Seoulense Nakai, including five phenanthrene derivatives (1–5), three isobutyl amides (6–8), three phenylpropanoids (9–11) and three lignins (12–14). The structures of these compounds were identified by spectroscopic methods and by comparison with the reported spectroscopic data. Among them, compounds 6 and 11 were firstly reported from the family Aristolochiaceae, and compounds 3 and 4 were reported for the first time from the genus Asarum. Additionally, compounds 1, 2 and 8 were isolated from A. sieboldii Miq. var. Seoulense Nakai for the first time. These compounds have shown chemical relationships between A. sieboldii Miq. var. Seoulense Nakai and other species of Asarum as well as those found in the genus Aristolochia in the family Aristolochiaceae.

从Asarum sieboldii Miq的95％乙醇回流提取物中分离出十四种化合物。变种 Seoulense中井，包括五菲衍生物（1 - 5），三个异丁基酰胺（6 - 8），三个苯丙（9 - 11）和三个木质素（12 - 14）。这些化合物的结构通过光谱方法鉴定，并与报道的光谱数据进行比较。其中，化合物6和11是最早从马兜铃科中报道的，化合物3和4是首次从细辛属中报道。此外，化合物1，2和8从分离甲。sieboldii Miq。变种 汉城中井第一次。这些化合物显示出A. sieboldii Miq之间的化学关系。变种 Seoulense Nakai和其他细辛种以及在马兜铃科的马兜铃属中发现的那些。
