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(+)-syringare sinol(1),5α,8-αepidioxy-24(R)-methycholesta-6,22-dien-3-βol(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-dibromo-2-amino-benzaldehyde(9),heptadecanoic acid 2,3-dihydroxy-propyl ester(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。

Abstract: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(+)-syringare sinol(1),5α,8α-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-dibromo-2-aminobenzaldehyde(9),heptadecanoic acid 2,3-dihydroxy-propyl ester(10).Conclution: Compounds 1,2 and 6-10 were isolated from this plant for the first time.
