WebApr 19, 2024 · CIT-P 2 with m/z 225 resulted from the hydroxylation of CIT followed by the opening of the ring and the loss of carbon dioxide leading to the formation of citrinin H2. This reaction also occurred without the loss of carbon dioxide and led to the product CIT-P 5 with m / z 269 which is increasingly produced with higher potentials. WebMay 15, 2024 · Citrinin H1 and H2 are degradation products of citrinin that are formed by boiling citrinin solution. Approximately 5 µL of degraded citrinin solution (10 pmol/µl) was required for visual detection of citrinin with our minimum recommended amount as opposed to only 1 µL untreated citrinin solution (10 pmol/µl) ( Fig. S8 , SI).
