A rapid and sensitive method was developed for simultaneous quantification of multiple classes of phytohormones and some related metabolites in crude plant extracts without purification or derivatization. High-performance liquid chromatography and electrospray ionization-tandem mass spectrometry with multiple reaction monitoring were used to quantify auxins, cytokinins, abscisic acid, gibberellins, jasmonates, salicylates, and a number of related metabolites in crude plant extracts. The technology was applied to analyze biotic and abiotic stress-induced changes of phytohormones in Arabidopsis tissues, starting with 50-100mg fresh tissue. Biotic and/or abiotic stresses were shown to differentially affect levels of salicylic acid, jasmonic acid, indole-3-acetic acid, and benzoic acid, in comparison to their methyl esters. Compared with previous methods, sample preparation time and amount of sample required for analysis of phytohormones are reduced, and more classes of hormones are quantitatively profiled. Structurally diverse compounds from complicated biological matrices are determined with high selectivity and sensitivity.
