摘要:

采用正相硅胶柱色谱、反相硅胶柱色谱、半制备型高效液相色谱和Sephadex LH-20凝胶柱色谱等分离技术对仿刺参(Apostichopus japonicus)内脏中的化学成分进行分离和纯化。通过1H NMR、13C NMR、HSQC、HMBC、1H-1H COSY、HR-ESI-MS等波谱技术,结合文献数据比对,从仿刺参内脏95%乙醇提取液中鉴定出14个单体化合物,分别为(E)-dec-5-en-1-yl sulfate(1)、(Z)-dec-5-en-1-yl sulfate(2)、7-methyloctyl sulfate(3)、(S)-2,6-dimethylheptyl sulfate(4)、N-lactoyl-phenylalanine(5)、(1S,3S)-1-methyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid(6)、(1R,3S)-1-methyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid(7)、L-phenylalanine(8)、tyramine(9)、tryptamine(10)、L-tryptophan(11)、8-oxo-tryptamine(12)、3-(2-aminoethyl)-3-hydroxyindolin-2-one(13)、β-carboline(14)。其中,化合物1为新化合物,化合物5~14首次分离自仿刺参内脏。

Abstract:

To study the chemical constituents of the viscera of Apostichopus japonicus,column chromatography,such as silica gel,ODS columns,semipreparative HPLC,and Sephadex LH-20 column chromatography,has been used to isolate the secondary metabolites.Their structures were characterized on the basis of multiple spectrometric and spectroscopic techniques,including 1H NMR,13C NMR,HSQC,HMBC,1H-1H COSY,NOESY,and HR-ESI-MS.As a result,fourteen compounds were isolated from the 95% ethanol extract of the viscera of A. japonicus.These compounds were identified as (E)-dec-5-en-1-yl sulfate (1),(Z)-dec-5-en-1-yl sulfate (2),7-methyloctyl sulfate (3),(S)-2,6-dimethylheptyl sulfate (4),N-lactoyl-phenylalanine (5),(1S,3S)-1-methyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid (6),(1R,3S)-1-methyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid (7),L-phenylalanine (8),tyramine (9),tryptamine (10),L-tryptophan (11),8-oxo-tryptamine (12),3-(2-aminoethyl)-3-hydroxyindolin-2-one (13),β-carboline (14).Compound 1 was a novel compound.Compounds 5-14 were obtained from A. japonicus for the first time.
