Plant viral diseases are difficult to control and have caused serious damage to the agricultural industry. Recently, botanical biopesticides characterized by environment friendly, safe to non‐target organism and not as susceptible to produce drug resistance, have exhibited great potential to be developed as antiviral agents. To screen the natural products with antiviral effect, three alkaloids possessed anti‐tobacco mosaic virus (TMV) activity were isolated from Chelidonium majus and the modes of action were investigated.

从芜菁白屈菜中分离出的三种生物碱的抗TMV活性和作用方式。

植物病毒病难以控制，已严重破坏了农业。最近，以环境友好，对非靶标生物安全且不易产生耐药性为特征的植物性生物杀虫剂，具有开发作为抗病毒剂的巨大潜力。为了筛选具有抗病毒作用的天然产物，从白屈菜中分离了三种具有抗烟草花叶病毒（TMV）活性的生物碱，并研究了其作用方式。
