摘要: 以卤虫致死活性和HPLC-DAD图谱为指导,充分利用正相、反相色谱技术,对采自南海北部3536 m深的海底沉积放线菌Streptomyces sp.SCSIO 5604的活性次级代谢产物进行了研究,从中分离到一个吲哚内酰胺类化合物,经HR-ESI-MS、1H-NMR、13C-NMR波谱分析,确定其为lyngbyatoxin A。

Abstract: The strain SCSIO 5604 was identified to be Streptomyces sp.by 16S rRNA gene sequence,which was isolated from a sediment sample collected in South China Sea at E 120° 0.250′ and N 20° 22.971′ at 3536 m depth.Guided by brine shrimp lethality and HPLC-DAD,chemical analysis of the crude extract of the fermentation culture,led to the isolation of an indolelactam compound,namely lyngbyatoxin A.The structure of lyngbyatoxin A was identified based on the HR-ESI-MS, 1H-NMR,13C-NMR spectra and comparing with literature data.

Key words: marine actinomycete, Streptomyces sp., lyngbyatoxin A, brine shrimp lethality
