| Abstract: | A new mass spectrametry, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry was used for analysis of oligasaccharides in plants. Difiierent sample preparation methods and sample detecdon modes were compared. This paper presented the absolute molecular weight disbibudons and molecular weights of repeat units and end groups of oligasaccharides. |
