Abstract
The metabolism of deuterium-labeled (±)-jasmonicacid and 3-oxo-2-[(Z)pent-2′-enyl]-cyclopentan-1- octanoic acid in potato (Solanum tuberosum L.) was examined by using cultures of potato single-node stems. Deuterium-labeled (±)-jasmonic acid and 3-oxo-2-[(Z) pent-2′-enyl]cyclopentan-1-octanoic acid, which had been prepared from commercially available methyl (±)-jasmonate, were fed to the cultures, and the metabolites were extracted from the plants and analyzed by a liquid chromatography-selected ion monitoring system. The metabolism of deuterium-labeled (±)-jasmonic acid and 3-oxo-2-[(Z)-2′-pentenyl]cyclopentan-1-octanoic acid to 5′ and 4′-O-glucopyranosyloxyjasmoic acids was strongly suggested.
