title: The influence of the cationic of quaternized chitosan on antifungal activity.
abstract: Quaternized chitosan: N-(2-hydroxyl-phenyl)-N,N-dimethyl chitosan (NHPDCS), N-(5-chloro-2-hydroxyl-phenyl)-N,N-dimethyl chitosan (NCHPDCS), N-(2-hydroxyl-5-nitro-phenyl)-N,N-dimethyl chitosan (NHNPDCS) and N-(5-bromic-2-hydroxyl-phenyl)-N,N-dimethyl chitosan (NBHPDCS) were synthesized and their antifungal activities against Botrytis cinerea Pers. (B. cinerea Pers.) and Colletotrichum lagenarium (Pass) Ell.et halst (C. lagenarium (Pass) Ell.et halst) were investigated. The results indicated that the quaternized chitosan derivatives had better inhibitory effects than chitosan, and the antifungal activities should be affected by the cation in these compounds.
