Gas chromatography-mass spectrometry (GC-MS)-based analysis is an accurate and sensitive method to quantify plant hormones. This method is commonly used for analysis of low-molecular-weight compounds, such as abscisic acid (ABA), gibberellins (GAs), auxins, and brassinosteroids. Procedures are composed of four major steps: extraction, fractionation, derivatization, and detection. Here, we describe a protocol for quantification of ABA and GAs.

UI MeSH Term Description Entries
D010937 Plant Growth Regulators Any of the hormones produced naturally in plants and active in controlling growth and other functions. There are three primary classes: auxins, cytokinins, and gibberellins. Phytohormone,Phytohormones,Plant Growth Regulator,Plant Hormone,Plant Hormones,Growth Regulators, Plant,Regulators, Plant Growth,Growth Regulator, Plant,Hormone, Plant,Hormones, Plant,Regulator, Plant Growth
D010944 Plants Multicellular, eukaryotic life forms of kingdom Plantae. Plants acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations. It is a non-taxonomical term most often referring to LAND PLANTS. In broad sense it includes RHODOPHYTA and GLAUCOPHYTA along with VIRIDIPLANTAE. Plant
D002849 Chromatography, Gas Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.

D005875 Gibberellins A class of plant growth hormone isolated from cultures of GIBBERELLA FUJIKUROI, a fungus causing Bakanae disease in rice. There are many different members of the family as well as mixtures of multiple members; all are diterpenoid acids based on the gibberellane skeleton. Gibberellin
D000040 Abscisic Acid Abscission-accelerating plant growth substance isolated from young cotton fruit, leaves of sycamore, birch, and other plants, and from potatoes, lemons, avocados, and other fruits. 2,4-Pentadienoic acid, 5-(1-hydroxy-2,6,6-trimethyl-4-oxo-2-cyclohexen-1-yl)-3-methyl-, (S-(Z,E))-,Abscisic Acid Monoammonium Salt, (R)-Isomer,Abscisic Acid, (+,-)-Isomer,Abscisic Acid, (E,E)-(+-)-Isomer,Abscisic Acid, (E,Z)-(+,-)-Isomer,Abscisic Acid, (R)-Isomer,Abscisic Acid, (Z,E)-Isomer,Abscissic Acid,Abscissins
