摘要

In the present study, evaluated was the paralysis activity of whole Italian and Algerian Melia azedarach, commonly known as chinaberry, fruits and parts (seeds, wood, and kernels) against Meloidogyne incognita second stage juveniles (J2)- The paralysis activity was evaluated in vitro after 1 h and 1 day immersion periods of nematodes in test solutions. Phenolic constituent components of the extracts were identified and quantified by high-performance liquid chromatography—mass spectrometry, while confirmation was performed by high-performance liquid chromatography—diode array. The water extract of the. Italian M. azedarach fruit pulp (IPWE) showed significant nematicidal activity (EC_(50/48h) = 955 μg/mL) and among its active ingredient components were p-coumaric acid and p-hydroxybenzoic acid (EC_(50/48h) = 840 and 871 μg/mL, respectively). This is the first report of the nematicidal activity of M. azedarach pulp water extract and phenolic acids against the root knot nematode M. incognita.
