Determination of neurotoxic agents as markers of common vetch adulteration in lentil by LC-MS/MS.

Vicia sativa (common vetch), which contains β-cyanoalanine (BCA) and γ-glutamyl β-cyanoalanine (γGBCA) is used for adulteration of lentil and have neuro toxic effects on people and animals. Therefore the determination of BCA and γGBCA analytes in accurate and reliable manner has high importance for human and animal health. LC-IDMS/MS method has been developed and validated for quantitative analyses of β-cyanoalanine and C labeled BCA is used as an internal standard in γGBCA analysis.
