Eight compounds 1-8 were obtained from the fermentation broth and mycelium of B-2 through modern methods for isolation and purification in order to research secondary metabolites from coral-derived endophytic bacteria Pelomonas puraquae sp. nov(B-2) . Their structures were analyzed by
1
H and
13
-C NMR
MS and physical methods. The results indicated that they were composed of 8 compounds including cyclo(Hyp-Phe)(1)
cyclo(Pro-Tyr)(2)
cyclo(Phe-Gly)(3)
cyclo(Phe-Ala)(4)
cyclo(Ala-Tyr)(5)
cyclo(Leu-Gly)(6)
cyclo(Gly-Val)(7) and cyclo(Ala-Val)(8). They were all cyclodipeptides and first acquired from the coralderived endophytic bacteria Pelomonas puraquae sp. nov(B-2).
