Rotenone

Japanese: ロテノン(英語表記)rotenone
Rotenone
A colorless crystal with insecticidal properties obtained from the roots of derris and coube plants native to tropical regions, such as Lonchocarpus spp. It is practically insoluble in water, but dissolves easily in acetone and chloroform. Indigenous peoples of the Malay Peninsula and South America used it as a poison added to water to catch fish. As a botanical insecticide, it is used especially against monkey beetles and cucumber flies. It is used as derris powder and derris emulsion. Its toxic effect on living organisms comes from its inhibition of oxidative phosphorylation in mitochondria, and it is also widely used as an inhibitor for research purposes.

熱帯地方原産のマメ科の植物デリスやクーベ Lonchocarpus spp.などの根から得られる殺虫作用のある無色の結晶。水にほとんど溶けず,アセトン,クロロホルムなどに溶けやすい。マレー半島や南アメリカの先住民は魚をとるため水に加える毒物として用いていた。植物性殺虫剤としては,特にサルハムシ類,ウリバエ類に対して使う。デリス粉,デリス乳剤などとして使用する。生体への毒作用はミトコンドリアでの酸化的リン酸化を阻止することからきていて,研究用阻害剤としても広く利用されている。
