| 摘要: |
| [目的]研究柳珊瑚Anthogorgia caerulea共生细菌Bacillus methylotrophicus发酵液中的化学成分。[方法]采用多种柱色谱和高效液相色谱分离技术,对柳珊瑚A.caerulea共生菌B.methylotrophicus发酵液中化学成分进行研究,运用理化和波谱分析方法鉴定其化学结构。[结果]从共生细菌B.Methylotrophicus发酵液中分离了6个化合物,分别鉴定为环(脯-甘)二肽(1)、环(S-脯-R-亮)二肽(2)、胸苷(3)、尿苷(4)、原儿茶酸(5)、3-Furancarboxylic acid-5-(hydroxmenthy)-Furan(6)。[结论]化合物1~6均是首次从该种细菌中分离得到,丰富了柳珊瑚共生菌B.methylotrophicus的化学多样性。 |

| Abstract: |
| [Objective] To investigate the chemical constituents of the fermentation liquid from marine gorgonian-associated bacterium Bucillus methylotrophicus.[Method] The compounds were isolated and purified by column chromatography on silica gel and their structures were identified by spectral analyses and comparison with literatures.[Result] Six compounds were obtained from the fermentation liquid of B.methylotrophicus and characterized as Cyolo-(Pro-Gly) (1), Cyolo-(S-pro-R-leu) (2), Thymidine (3), Uridine (4), Protocatechuic acid (5), 3-Furancarboxylic acid-5-(hydroxmenthy)-Furan (6).[Conclusion] Compounds 1~6 were isolated from B.methylotrophicus for the first time, which enriches the chemical diversity of marine gorgonian-associated bacterium Bucillus methylotrophicus. |
