合成了N-（2-羟基苯基）- nn -二甲基壳聚糖（NHPDCS）、N-（5-氯-2-羟基苯基）- nn -二甲基壳聚糖（NCHPDCS）、N-（2-羟基-5-硝基苯基）- nn -二甲基壳聚糖（NHNPDCS）和N-（5-溴-2-羟基苯基）- nn -二甲基壳聚糖（NBHPDCS），并对其抑菌活性进行了研究。（B. cinerea Pers.）和Colletotrichum lagenarium (Pass) Ell。对C. lagenarium (Pass) Ellet halst进行了调查。结果表明，季铵化壳聚糖衍生物的抑菌效果优于壳聚糖，其抑菌活性可能受其阳离子的影响。(C) 2007 Elsevier B.V.版权所有
Quatemized chitosan: N-(2-hydroxyl-phenyl)-NN-dimethyl chitosan (NHPDCS), N-(5-chloro-2-hydroxyl-phenyl)-NN-dimethyl chitosan (NCHPDCS), N-(2-hydroxyl-5-nitro-phenyl)-NN-dimethyl chitosan (NHNPDCS) and N-(5-bromic-2-hydroxyl-phenyl)-NN-dimethyI 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) Ellet 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.
