The protein and non protein parts present in the leaves of Lippia nodiflora were separated and test their nematicidal activity against egg hatching and juvenile mortality of Meloidogyne incognita. The non protein part was found to inhibit the root knot nematode egg hatching under in vitro conditions. Leaf extraction was done with different solvent such as petroleum ether, chloroform methanol using soxhlet apparatus and the residue was discarded. Thin layer chromatography method was used to isolate and identify the nematicidal principle present in Lippia nodiflora. The identified compounds in non protein parts such as phenols, alkaloids and terpenoids were tested for their nematicidal activity on egg hatching and mortality of M. incognita juveniles. The nematicidal assay of these compounds revealed that the alkaloids inhibited egg hatching absolutely and caused juvenile mortality followed by phenols. The terpenoids did not show any marked inhibition on hatching of eggs and causing mortality of juveniles of M. incognita.
