Abstract:
OBJECTIVETo investigate the chemical constituents of Dendrobium chrysotoxum.
METHODThe chemical constituents were isolated by various column chromatographic methods and structurally elucidated by spectral evidences.
RESULTTen compounds were obtained and identified as (+)-syringare sinol (1), 5alpha, 8alpha-epidioxy-24( R)-methycholesta-6, 22-dien-3beta-ol (2), trans-3-(4-hydroxy-3-methoxyphenyl)-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).
CONCLUSIONCompounds 1, 2 and 6-10 were isolated from this plant for the first time.
