摘要 目的:研究鼓槌石斛的化学成分。方法:采用硅胶及Sephadax LH-20凝胶柱色谱法分离化合物,运用波谱学方法确定结构。结果:从鼓槌石斛中分离得到10个化合物,分别为(+).syrinsare sinol(1),5a,8a-epidioxy.24(R)-methycholesta-6,22-dien-β-ol(2),trans-3-(4-hydroxy-3-methoxy-phenyl)-acrylic acid octacosyl ester(3),defusin(4),3,4-dihydroxy-benzoicacid(5),3,4-dimethoxy-benzoic acid(6),vanillicacid(7),3,4-dimethoxy-benzoic acid methyl ester(8),3,5.dibromo-2-amino-benzaldehyde(9),heptadecanoic acid2,3-dihydroxy-propylester(10)。结论:化合物1,2及6-10均为首次从鼓槌石斛中分离得到。 Objective: To investigate the chemical constituents of Dendrobium chrysotoxum. Method: The chemical constituents were isolated by various column chromatographic methods and structurally elucidated by spectral evidences. Result: Ten compounds were obtained and identified as ( + )-syringam sinol (1), 5a, 8a-epidioxy-24( R)-methycholesta-6, 22-dien-3β-ol (2), trans-3-(4-hydroxy-3-methoxy- phenyl)-acrylic acid octacosyl ester (3), defusin (4), 3, 4-dihydroxy benzoic acid (5), 3, 4-dimethoxy-benzoic acid (6), vanillic acid (7), 3, 4- dimethoxy-benzoic acid methyl ester (8), 3, 5-dibremo-2-aminobenzaldehyde (9), heptadecanoic acid 2, 3-dihydroxy-propyl ester (10).Conclusion Compounds 1, 2 and 6-10 were isolated from this plant for the first time.
