摘　　要：以杨梅素为先导化合物,设计合成了12个酰胺类杨梅素衍生物;利用核磁共振波谱(~1H NMR和^(13)C NMR)和高分辨质谱仪(HRMS)对其结构进行了确证.初步抑菌活性测定结果表明,该类化合物对水稻白叶枯病菌、柑橘溃疡病菌和烟草青枯病菌均具有一定的抑制活性,化合物3a,3e,3f,3h和3k对3种植物病菌表现出较好的抑制活性,其中200μg/mL化合物3e对水稻白叶枯病菌和烟草青枯病菌的抑制活性均为100%,超过对照药叶枯唑(抑菌活性分别为72.85%和75.86%).Twelve novel myricetin derivatives containing acidamide moiety were designed and synthesized from myricetin. All the compounds were characterized by 1H NMR, 13C NMR and HRMS. The preliminary bioassay results indicated that all of the title compounds exhibited a certain antibacterial activities in vitro against X. oryzae, X. cirri and R. solanacearum. Moreover, These title compounds 3a, 3e, 3f, 3h and 3k displayed good antibacterial activities against the above three plant pathogenic bacteria. Especially, compound 3e displayed 100% inhibition rates against X. oryzae and R. solanacearum at 200 μg/mL, respectively, which is more than the control bismerthiazol（72. 85% and 75.86%, repectively）.
