ABSTRACT

Сhitosan-ferulic acid conjugates were synthesized by carbodiimide method and characterized by UV and FTIR spectroscopy. It has been determined that by varying the ratio of components during synthesis it is possible to obtain conjugates with desired ferulic acid content up to 50 μg ferulic acid/1 mg chitosan. Positively charged (zeta potential ~ +20.0 mV) hydrogel particles based on the obtained chitosan-ferulic acid conjugates were formed by ionotropic gelation and their physicochemical properties and phytotoxicity were evaluated.

基于壳聚糖-阿魏酸偶联物的水凝胶颗粒的合成及性能

摘要

通过碳二亚胺法合成壳聚糖-阿魏酸结合物，并通过紫外和红外光谱进行表征。已经确定，通过在合成过程中改变组分的比例，可以获得具有高达 50 μg 阿魏酸/1 mg 壳聚糖的所需阿魏酸含量的缀合物。基于获得的壳聚糖-阿魏酸缀合物的带正电荷（zeta 电位~+20.0 mV）水凝胶颗粒通过离子型凝胶化形成，并评估了它们的理化性质和植物毒性。
