Anthelmintic activity of some sudanese medicinal plants

The anthelmintic activity of aqueous extracts (0.25 mg/mL) from 14 plant species that represent seven families of the Sudanese flora was examined using the free living rhavditid nematode, Caenorhabditis elegans as a test organism. Extracts of Balanites aegyptiaca and Sesbania sesban were the most effective (LC 50 , 0.8 an,d 8.0 mg/mL, respectively). Extracts of Albizzia anthelmintica, Cympopogen narvatus, Abrus precatorius, Rhyncosia minima, Striga hermonthica and Anogeissus leiocarpa (LC 50 , 9.5-84.6 mg/ml were less effective in this model test system. Extracts of six plant species, Albizzia malacophylla, Gardenia lutea, Physostigma mesoponticum, Salvadora persica, Xeromphis nilotica and Waltheria indica had no effect upon C. elegans survival
