Abstract EN
The structure modification of chitosan has great application potential.
6-Oxychitosan was prepared by specially oxidizing the C6-OH of chitosan, then 6-oxychitosan was reacted with three kinds of aldehydes to prepare N-quaternized 6-oxychitosan derivatives in this paper.
The derivatives were characterized by FT-IR, NMR, and elemental analysis.
The antimicrobial activity of these derivatives was tested against two common plant-threatening fungi and three plant disease bacteria.
The results showed that N-quaternized 6-oxychitosan derivatives had good water-solubility and excellent antimicrobial activity.
Moreover, derivative 3 which connected 8-hydroxyquinolines had the highest antimicrobial activity than the other derivatives.
The inhibitory indices of derivative 3 against V.
albo-atrum and P.
hibernalis are 89.1% and 72.8% at 0.4 mg/ml.
The MICs of 3 against X.
oryzae, P.
syringae, and E.
rhapontici were 625, 625, and 156 mg/l, respectively.
All the results indicate that derivative 3 has the potential of becoming an alternative to harmful agricultural chemicals.
