Jasmonic acid is not a biosynthetic intermediate to produce the pyrethrolone moiety in pyrethrin II.

ABSTRACT: Pyrethrum (Tanacetum cinerariifolium) produces insecticidal compounds known as pyrethrins. Pyrethrins are esters; the acid moiety is either trans-chrysanthemic acid or pyrethric acid and the alcohol moiety of pyrethrins is either pyrethrolone, cinerolone, or jasmolone. It was generally accepted that cis-jasmone was biosynthetic intermediate to produce the alcohol moieties of pyrethrin, and the biosynthetic origin of the cis-jasmone was postulated to be jasmonic acid. However, there was no direct evidence to prove this hypothesis. In order to uncover the origin of pyrethrolone moiety in pyrethrin II, feeding experiments were performed employing deuterium- and ¹³C-labeled compounds as substrates, and the expected labeled compounds were analyzed using UPLC MS/MS system. It was foun
