What is "deguelin"

n. A rotenone derivative and naturally-occurring insecticide.

Deguelin is a derivative of rotenone. Both are compounds classified as rotenoids of the flavonoid family and are naturally occurring insecticides. They can be produced by extraction from several plant species belonging to three genera of the Fabaceae or Legume family, Lonchocarpus, Derris, or Tephrosia.

Cubé resin, the root extract from Cubé ( Lonchocarpus utilis) and from Barbasco ( Lonchocarpus urucu), is used as a commercial insecticide and piscicide (fish poison). The major active ingredients are rotenone and deguelin. Although "organic" (produced by nature) cubé resin is no longer considered environmentally safe.
