| Abstract: | Objective]To investigate the secondary metabolites of marine bacterium Bacillus sp.753 by various modern spectrum methods.Methods]Constituents in the fermentation liq-uid of the marine bacteria were isolated and purified by silica gel,Sephadex LH-20,and semi-preparative reverse-phase HPLC (C18 ).Their structures were identified by NMR,MS and lit-eratures.Results]Twelve compounds were iso-lated from marine bacterium Bacillus sp.753 and their structures were identified as uridine (1 ), thymine (2),cyclo-(phe-lle)(3),cyclo-(ala-pro) (4),cyclo-(val-pro)(5),cyclo-(pro-leu)(6),cy-clo-(phe-pro)(7),cyclo-(tyr-pro)(8),cyclo-(tyr-4-hydroxy-pro)(9),cyclo-(leu-pro)(10), cyclo-(pro-4-hydroxyl-lle)(11),cyclo-(D-pipecolinyl-L-leucine)(12).Conclusion]Com-pounds 1~1 2 were isolated from this bacterium for the first time,which not only enriched the types of chemical composition in the Bacillus sp.753,but also increased the research val-ue of the marine bacterium. |
