摘要：

Mild hydrazinolysis of Pseudomonas fluorescens strain ATCC 49271 lipopolysaccharide (LPS) followed by strong alkaline degradation and purification by anion-exchange HPLC resulted in two phosphorylated oligosaccharides (1 and 2). On the basis of compositional analysis and H-1, C-13, and P-31 NMR spectroscopy, including 2D correlation spectroscopy (COSY), 2D rotating frame NOE spectroscopy (ROESY), and 2D inverse mode H-detected heteronuclear H-1-C-13 and H-1-(31)p correlation spectroscopy, the following two structures (1 and 2) could be identified
