pyrethrins toxicity. Pyrethrins are natural apolar esters that are solvent-extracted from the flower heads of Chrysanthemum cineraiaefolium. They are excellent insecticides with low toxicity to mammals due to their poor absorption and rapid metabolism to non-toxic metabolites. The pyrethrins are a class of organic compounds normally derived from Chrysanthemum cinerariifolium that have potent insecticidal activity by targeting the nervous systems of insects. Pyrethrins are pesticides found naturally in some chrysanthemum flowers. They are a mixture of six chemicals that are toxic to insects. Pyrethrins are commonly used to control mosquitoes, fleas, flies, moths, ants, and many other pests. Pyrethrins are generally separated from the flowers.
This comprehensive scientific review provides an in-depth analysis of both the natural compounds, pyrethrins, and their synthetic derivatives, pyrethroids, focusing on their classification, biosynthesis, mechanism of action, general and ... Pyrethrins (Figure 1) and pyrethroids (Figure 2) are synthetic ester compounds, used in insecticides, and are derived from naturally occurring substances of plants such as the Dalmatian Pellitory flower (Chrysanthemum cinerariaefolium). The extract contains about 50% active insecticidal ingredients known as pyrethrins. The ketoalco-holic esters of chrysanthemic and pyrethroic acids are known as pyrethrins, cinerins and jasmolins. These strongly lipophilic esters rapidly penetrate many insects and paralyze their nervous systems.
