520	3		_aA mass spectrometerwas coupled to high-performance ligand-exchange liquid chromatography (HPLEC)for simultaneous analysis of stress associated solutes such as proline, hydroxyproline, methylproline, glycine betaine and trigonelline extracted from leaves of drought stressed oaks and an internal standard namely N-acetylproline. Methanol/chloroform/water extracts were analyzed using an Aminex HPX-87C column and specifically quantified by the positive ion mode of an electrospray ionisation-mass spectrometry (ESI-MS)in single ion monitoring (SIM)mode. The recovery of N-acetyl proline added to oak leaf extracts ranged from 85.2 to 122.1
