Abstract
Potato glycoalkaloids are produced in high amounts in potato fields during the growth season and losses to soil potentially impact shallow groundwater and via tiles to fresh water ecosystems. A quantitative liquid chromatography–electrospray ionization time-of-flight mass spectrometry (LC–ESI-TOF-MS) method for determination and quantification of potato glycoalkaloids and their metabolites in aqueous soil extracts was developed. The LC–ESI-TOF-MS method had linearities up to 2000 μg/L for α-solanine and α-chaconine and up to 760 μg/L for solanidine. No matrix effect was observed, and the detection limits found were in the range 2.2–4.7 μg/L. The method enabled quantification of the potato glycoalkaloids in environmental samples.
