Jasmonic acid, methyl jasmonate, and salicylic acid have been reported to occur in plants and are thought to be essential for the regulation of systemic defence responses. Inclusion during sample preparation of hydrogenated and/or deuterated internal standards corresponding to analogues of the regulators compensate for sample loss and permit quantification using the multiple reaction monitoring mode of the mass spectrometer.
