title: Novel acetylated alpha-cyclosophorotridecaose produced by Ralstonia solanacearum.
abstract: Alpha-cyclosophorotridecaose (alpha-C13) produced by Ralstonia solanacearum is isolated by trichloroacetic acid treatment and subjected to various chromatographic techniques. Here, we report for the first time that R. solanacearum produces acetylated alpha-C13. Structural analyses of the acetylated alpha-C13 were performed with 1D or 2D NMR spectroscopy, MALDI-TOF MS and HPLC. The results show that the alpha-C13 is substituted by mainly one acetyl residue at the C-6 position of the glucose unit.
