The invention relates to a quinoline group-containing chitosan oligosaccharide quaternary ammonium salt derivative and a preparation method and application thereof
The invention relates to the technical field of marine chemical engineering, in particular to a quinoline group-containing chitosan oligosaccharide quaternary ammonium salt derivative and a preparation method thereof, and application of the quaternary ammonium salt derivative in the fields of medicine, functional food health care, cosmetics and the like. The quinoline group-containing chitosan oligosaccharide quaternary ammonium salt derivative has a structure shown in a formula I. The quinoline group-containing chitosan oligosaccharide quaternary ammonium salt derivative has the advantages that the quinoline group is grafted into the chitosan oligosaccharide through a chemical method, so that the biological activity of the chitosan oligosaccharide is improved, the preparation process is simple, side reactions are few, and the used material cost is low. Researches prove that the derivative has good water solubility, good antioxidant activity and bacteriostatic activity, and wide application value in medicine, functional food health care, especially cosmetics industry. Formula I.
