Abstract Reinvestigation of the polar fractions of the aerial parts of Centaurea ruthenica afforded, in addition to known compounds, more than 20 new ones, mostly in very small quantities, which in many cases could only partly be separated even after acetylation. The structures, however, could be elucidated by spectroscopic methods. Besides additional C 13 -acetylenes, several new C 14 - and C 10 -acetylenes
摘要 重新研究 Centaurea ruthenica 地上部分的极性部分,除了已知化合物外,还提供了 20 多种新化合物,大部分是非常少量的,在许多情况下,即使在乙酰化后也只能部分分离。然而,这些结构可以通过光谱方法阐明。除了额外的 C 13 - 乙炔外,还存在几种新的 C 14 - 和 C 10 - 乙炔。鉴于所提出的此类炔属化合物的生物合成方案,所分离的化合物特别令人感兴趣。
