Isolation and characterisation of nematicidal compound, leolorin C, from Leonotis leonurus acetone leaf extract

Natural nematicidal metabolites and advances in their biocontrol capacity on plant parasitic nematodes

“…Leoleorin C 161 was isolated from Leonotis leonurus and demonstrated activity against C. elegans ; however, it was not active against M. incognita . 76 Two metabolites, 8-epidiosbulbin e acetate 162 and diosbulbin B 163 , were obtained from Aristolochia tuberosa and exhibited obvious toxic effects against M. javanica . 77 A novel tetranorlabdane diterpenoid, botryosphaerins H 164 , was identified from Botryosphaeria species P483, and exhibited activity against P. redivivus and C. elegans .…”

The activity of leaf extracts, fractions, and isolated compounds from Ptaeroxylon obliquum against nine phytopathogenic fungi and the nematode Meloidogyne incognita

“…Plant extracts or secondary metabolites constitute a major source of bioactive substances against pathogenic fungi. Many studies from the Phytomedicine Programme at the University of Pretoria have reported on the antifungal and antiparasitic activities of plant extracts and isolated compounds against dangerous fungi and parasites of plant, humans and animals [ 24 , [32] , [33] , [34] , [35] , [36] , [37] , [38] , [39] , [40] ]. Because plants contain different classes of secondary metabolites these compounds may have a novel mechanism of action that may minimize the development of resistance by the pathogens [ 22 ].…”
