摘　　要：首次报道了分离自杠板归(Polygonum perfoliatum)的12个单体化合物的抗烟草青枯病菌(Ralstonia solanacearum)和杀全齿复活线虫(Panagrellus redivivus)的活性。结果表明,4个黄酮、苯醌、生物碱等类型化合物对烟草青枯病菌有拮抗活性,7个三萜、甾体、黄酮、糖脂类成分具有杀线虫活性。杠板归对烟草青枯病菌和线虫具有化学防治功效,可为其相关农药研制提供依据。The toxicities against Ralstonia solanacearum and Panagrellus redivivus of twelve compounds isolated from Polygon- um perfoliatum were reported for the first time. Results showed that four compounds corresponding to three types of flavonoid, quinone, and alkaloid exhibited definite toxicities against R. solanacearum and 7 compounds including terpenoids, steroids, flavonoids and glycolipids had the marginal toxicities against P. redivivus. The study indicated that P. perfoliatum possessed the chemical control against R. solanacearum and P. redivivus, laying groundwork for development of relate pesticide from this plant.
