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.
