摘    要:目的:对环草石斛Dendrobium loddigesii的H-NMR指纹图谱进行解析。方法:应用硅胶柱色谱法分离环草石斛SCEA的化学成分,鉴定单体化合物的结构并对其进行1H-NMR研究,从而实现环草石斛的1H-NMR指纹图谱解析。结果:不同来源的环草石斛样品,其1H-NMR指纹图谱有很好的重现性和高度的特征性。从其SCEA中分得4个主要成分,经光谱分析鉴定了其结构,分别为moscatilin(1),moscatin(2),gigantol(3)和十八碳二烯酸单甘油酯(4)。结论:环草石斛的1H-NMR指纹图谱可用于其基源鉴定,并主要显示了以上4个化合物的特征共振信号;化合物3和4为首次从环草石斛分离鉴定。

关 键 词:环草石斛  H-NMR指纹图普

Abstract:Objective: To analyse the 1H-NMR finger-prim of the stem of Dendrobium loddigesii. Method: Silica gel column chromatography was used to separate the chemical constituents of SCE A of the stem of D. loddigesii. The characteristic signals of the H-NMR finger-print were analysed after determining the structures of the compounds isolated from SCE A. Result: 1H-NMR finger-prints of the samples of D. loddigesii collected from different regions showed highly characteristic features and reproducibility. Four compounds predominant in SCE A were isolated and their structures were determined by spectral analysis as 1, 2, 3 and 4, respectively. Conclusion: Compound 3 and 4 were isolated from D. loddigesii for the first time. The 1H-NMR finger-print of CGE A of the stem of D. loddigesii showed mainly the characteristic signals of the above four compounds and might be utilized for the original authentication of this plant.
Keywords:Dendrobium loddigesii  1H-NMR finger-print
