چکیده    The ethanol extract of chinese medicinal herb,evodia rutaecarpa hort unripe fruits,was found to possess nematocidal activity against the root-knot nematodes,meloidogyne incognita,during the screening program for new agrochemicals from local wild plants and chinese medicinal herbs. bioactivity-guided chromatographic separation of the ethanol extract of e. rutaecarpa on repeated silica gel columns led to isolate five constituent components (two limonoids,evodol and limonin; three alkaloids,evodiamine,rutaecarpine,and wuchuyuamide i). evodiamine (lc 50 = 73.55 g/ml) and rutaecarpine (lc 50 = 120.85 g/ml) exhibited stronger nematocidal activity against m. incognita than the crude ethanol extract of e. rutaecarpa (lc 50 = 131.54 g/ml). wuchuyuamide i,evodol,and limonin also possessed nematocidal activity against m. incognita with lc50 values of 147.87g/ml,155.02g/ml,and 197.37g/ml,respectively,but weaker than the crude ethanol extract of e. rutaecarpa. © 2013 qi zhi liu et al.
