Abstract Here, we isolated a new polyacetylene, (2Z,8E)-heptadecadiene-10-oxo-4,6-diyn-1-ol (1), an oxylipin (2), eight phenolic compounds (3–10), and 15 saponins (11–25) from the roots of Bupleurum chinense. We elucidated their structures by analysis of 1D and 2D-NMR spectroscopic data and mass spectrometry, and by comparison with those of related metabolites. This is the first report of the presence of compounds 2 and 6 in the Bupleurum spp.. Chemotaxonomic significance of these compounds is described herein.

柴胡新聚乙炔等化合物及其化学分类学意义

摘要 在这里，我们分离出了一种新的聚乙炔、(2Z,8E)-heptadecadiene-10-oxo-4,6-diyn-1-ol (1)、一种oxylipin (2)、八种酚类化合物 (3-10) 和来自柴胡根的 15 种皂苷 (11–25)。我们通过分析 1D 和 2D-​​NMR 光谱数据和质谱，并通过与相关代谢物的比较来阐明它们的结构。这是柴胡属中存在化合物2和6的首次报道。本文描述了这些化合物的化学分类学意义。
