摘要
<img src="http://www.sciencedirect.com/scidirimg/entities/204e.gif" alt="greek small letter alpha" title="greek small letter alpha" border="0">-Cyclosophorotridecaose (<img src="http://www.sciencedirect.com/scidirimg/entities/204e.gif" alt="greek small letter alpha" title="greek small letter alpha" border="0">-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 <img src="http://www.sciencedirect.com/scidirimg/entities/204e.gif" alt="greek small letter alpha" title="greek small letter alpha" border="0">-C13. Structural analyses of the acetylated <img src="http://www.sciencedirect.com/scidirimg/entities/204e.gif" alt="greek small letter alpha" title="greek small letter alpha" border="0">-C13 were performed with 1D or 2D NMR spectroscopy, MALDI-TOF MS and HPLC. The results show that the <img src="http://www.sciencedirect.com/scidirimg/entities/204e.gif" alt="greek small letter alpha" title="greek small letter alpha" border="0">-C13 is substituted by mainly one acetyl residue at the C-6 position of the glucose unit.
