摘　　要：为了进一步提高壳聚糖用于涂膜时的综合抗菌能力,采用滤纸片法及菌丝扩展法测定并对比了丁香油和百里酚对桃采后致病褐腐菌的抗菌能力及用微孔板法测定了它们的最小抑菌浓度,并将丁香油、百里酚复合壳聚糖对桃果进行涂膜,测量果体经过涂膜和接菌后的病斑扩展。结果表明丁香油和百里酚都具有较好的抗褐腐菌能力,百里酚强于丁香油,复合壳聚糖涂膜时二者都可以提高壳聚糖总体抗菌能力且复合百里酚效果较好。二者具有作为壳聚糖涂膜保鲜添加剂的应用潜力。In order to increase the total antibacterial capacity of chitosan coating on the fruits,the antibacterial effects of coating-treated peach fruit by eugenia oil,thymol and the eugenia-thymol combination were comparaed.The effects were evaluated by the extent of the pathological spot changes and minimum antibacterial concentrations.The test results showed that the eugenia and thymol all had better anti-monilining fructicola effect and the thymol had better effect than eugenia oil.Moreover,the effect of combination of eugenia and thymol was better than the single ones.The eugenia and thymol both had the application potential for the fruit preservation coating.
