| titleOfInvention | Heterocyclic chitosan oligosaccharide derivative and synthesis method thereof |
| abstract | The invention provides a heterocyclic chitosan oligosaccharide derivative and a synthesis method thereof, and the specific steps are as follows: (1) adding a heterocyclic compound into ethanol for dissolving, adding cetyl trimethyl ammonium bromide and sodium hydroxide when the solution is clear, stirring at normal temperature, dropwise adding epoxy chloropropane, stirring for 1.5-3h, and stopping reaction until white solid appears and is not increased any more, so as to obtain a solid-liquid mixture; (2) dissolving chitosan oligosaccharide in distilled water, adding the solid-liquid mixture obtained in step (1), stirring at constant temperature of 60-80 deg.C for 3-5h, cooling to room temperature, adding ethanol, standing for 12-15h, filtering under reduced pressure to obtain solid, washing the solid with ethanol twice, and drying in a drying oven. The heterocyclic chitosan oligosaccharide derivative prepared by the invention has good antibacterial activity and certain inhibition effect on tobacco black shin and corn green withered. The heterocyclic chitosan oligosaccharide derivative has good fat solubility and water solubility, is easy to be absorbed by plants, and has high activity. |
