Metabolism of deuterium-labeled jasmonic acid and OPC 8:0 in the potato plant (Solanum tuberosum L.)

The metabolism of deuterium-labeled (=+-)-jasmonic acid and 3-oxo-2-[(Z)pent-2' -enyll-cyclopentan-1-octanoic acid in potato (Solanum tuberosum L.) was examined by using cultures of potato single-node sterns. 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.
