Abstract
Pyrethrins I and II were extracted from five seasonal Compositae herbs collected from semi-arid and hilly areas of North India. The relative toxicity of natural pyrethrins were evaluated against Mesocyclops leuckarti sensu lato. Based on the LC50 values, the extract of the plants could be arranged as follows: Tageles minuta > Pulicaria crispa > T. patula > T. minuta > P. angustifolia.
Résumé
Perythrin I et Perythrin II furent extraits de cinq plantes composites collectées dans les regions semi-arides et montagneuses du Nord de l’Inde. La toxicité relative du Perythrin naturel etait evaluée contre le Mesocyclops leuckarti sensu lato. En considerant la valeur du LC50, les extraits de ces plantes peuvent être classifier comme suit: Tagetes minuta > Pulicaria crispa > T. patula > T. minuta > P. angustifolia.
