<dc:description>Mandelonitrile is a nitrogen-containing compound, considered an essential secondary metabolite. Chemically, it is&#xd;
a cyanohydrin derivative of benzaldehyde, with relevant functions in different physiological processes including&#xd;
defense against phytophagous arthropods. So far, procedures for detecting mandelonitrile have been effectively&#xd;
applied in cyanogenic plant species such as Prunus spp. Nevertheless, its presence in Arabidopsis thaliana,&#xd;
considered a non-cyanogenic species, has never been determined. Here, we report the development of an accurate&#xd;
protocol for mandelonitrile quantification in A. thaliana within the context of A. thaliana–spider mite interaction.&#xd;
First, mandelonitrile was isolated from Arabidopsis rosettes using methanol; then, it was derivatized by silylation&#xd;
to enhance detection and, finally, it was quantified using gas chromatography–mass spectrometry. The selectivity&#xd;
and sensitivity of this method make it possible to detect low levels of mandelonitrile (LOD 3 ppm) in a plant species&#xd;
considered non-cyanogenic that, therefore, will have little to no cyanogenic compounds, using a small quantity of&#xd;
starting material (≥ 100 mg).</dc:description>
