Preparation and Purification and Analysis of Chito-oligosaccharide and Its Application in Agriculture

This article reviewed the research progress in the preparation and purification and analysis of chito-oligosaccharide and its application in agriculture, especially in inhibiting planted disease. Chito-oligosaccharide may be also used as soil amendment and inducer of resistant to plant disease. The preparation methods of chito-oligosaccharide are chemical process, zymolysis and physical method. The purification can be carried out by chromatographic column seperation, membrane seperation and enzymatic method. The application of new techniques in analysis, such as high performance liquid chromatography, mass spectrographic, nulcear magnetic ressonance and infrared spectrum, was also described.
