摘　　要：Two aminooligosaccharides. isovalertatins D03 (1) and D23 (2). were isolated from the culture filtrate of Streptomyces luteogriseus. Their structures were reinvestigated and revised by spectroscopic evidences including ESI multistage mass spectrometry and 2-dimensional NMR techniques.Two aminooligosaccharides. isovalertatins D03 (1) and D23 (2). were isolated from the culture filtrate of Streptomyces luteogriseus.
