- Abstract
- An algorithm for two-step detection of muscarinic, ibotenic acid and muscimol in urine samples is described. A two-step method for the detection of muscarinic, muscimol and ibotenic acid in data-dependent MRM analysis mode with simultaneous registration of complete mass spectra of the target substances was developed. Detection of analytes was carried out by HPLC with a three-quadrupole mass spectrometric detector (LC-MS/MS Shimadzu 8050). Chromatographic separation was performed on a column with reversed-phase sorbent Phenomenex Kinetex C18. At the first stage, muscarine was detected in a diluted urine sample; at the second stage, muscimol and ibotenic acid were detected using the bimolecular dansylation method. The method was successfully applied in practice for routine chemical-toxicological studies of urine samples of patients delivered with suspected mushroom poisoning.
