文摘

The ethanol extract of Punica granatum L. rind had significant nematicidal activity against PWN, which was reported for the first time. Three tannins with different nematicidal activities were obtained by bioactivity-guided isolation and identified as punicalagin 1, punicalin 2, corilagin 3. Punicalagin 1 showed the strongest nematicidal activity. Punicalagin 1 could inhibit the activity of acetylcholinesterase, amylase and cellulase from PWN. The morphology of nematodes changed significantly after they were treated by punicalagin 1.
