OBJECTIVE To analyse the 1H-NMR finger-print 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.
