chrysanthemum cinerariifolium seeds

Pyrethrum plants in Kashmir
Pyrethrum was a genus of several Old World plants now classified as Chrysanthemum or Tanacetum (e.g., C. coccineum) which are cultivated as ornamentals for their showy flower heads. Pyrethrum continues to be used as a common name for plants formerly included in the genus Pyrethrum. Pyrethrum is also the name of a natural insecticide made from the dried flower heads of Chrysanthemum cinerariifolium and Chrysanthemum coccineum. Its active ingredient are pyrethrins.

Pyrethrum and pyrethrins are insecticides extracted from certain species of flowers in the chrysanthemum family. Pyrethrins are the 6 active molecules – or esters – that act as the killing agent in the extract. Pyrethrum is the total extract from the flowers, while pyrethrins are the refined 6 esters.

Pyrethrum seeds

Bot.name: Chrysanthemum cinerariifolium,Tanacetum cinerariifolium
Cashmerian name: Kartik posh
Other names: Dalmation Pellitory, Pyrethrum, Pyrethrum daisy,
Family: Compositae
Chemical constituents: The pyrethrins are a pair of natural organic compounds normally derived from Chrysanthemum cinerariifolium that have potent insecticidal activity. Pyrethrins are neurotoxins that attack the nervous systems of all insects. When present in amounts not fatal to insects, they still appear to have an insect repellent effect. Pyrethrins are gradually replacing organophosphates and organochlorides as the pesticide of first choice. They are non-persistent, being biodegradable, and break down on exposure to light or oxygen. The chemical structure of pyrethrins inspired the production of a variety of synthetic insecticides called pyrethroids such as bifenthrin, permethrin, and cypermethrin.
Six compounds were isolated and identified as: linoeic acid, pinoresinol, (+)-pinoresinol-4'-O-beta-D- glucopyranoside, betulabuside A, dihydrosyringin.

Medicinal use of Chrysanthemum cinerariifolium : Chrysanthemum cinerariifolium is not used medicinally, though research has shown that the flowers possess weak antibiotic activity. The flowers are the main source of the insecticide pyrethrum, which is toxic to insects but not to mammals. It has sometimes been used as a vermifuge in China.
