Jasmonic acid (JA) and its many derivatives-collectively referred as jasmonates-occur ubiquitously in land plants and regulate a wide range of stress-responses and development. Measuring these signaling compounds is complicated by the large number of jasmonate derivatives and the comparatively low concentration of these metabolites in plant tissues. We, here, present a selective and sensitive method consisting of a two-phase extraction coupled with liquid chromatography, nanoelectrospray ionization, and mass spectrometry to determine jasmonate levels in tissues and fluids of various plant species. The application of stable deuterium-labelled standards in combination with authentic standards allows the absolute quantification of a multitude of jasmonates and, additionally, the semi-quantitative analysis of further metabolites from the jasmonate pathway.
