摘要:

从菊科药用植物西北风毛菊(Saussurea Petrovii Lipsch)中首次分离得到一新的桉烷型倍半萜酯——西北风毛菊素 (petroviin). 采用1H-1H COSY、HMQC、HMBC及NOESY二维谱技术鉴定了此化合物的化学结构及构型, 并对其1H和13C NMR 的谱峰进行了全归属.

关键词: 西北风毛菊, 桉叶烷型倍半萜, 2D NMR

Abstract:

From the Inner Mongolia medicinal plant, Saussurea petrovii, which was coll ecte d in the suburb of Lanzhou city, Gansu province of China, a colourless gum compo und was isolated. The compound was identified as a new eudesmane type sesquiterp ene ester, petroviin, by MS and NMR. The structure of petroviin was determined b y two-dimensional NMR spectroscopy for the first time. All the 1H and 13C NMR resonances   were assigned unambiguously. The relative configuration of petroviin was also  evaluated.

Key words: saussurea petrovii, eudesmane, 2D NMR
