- •
Adulteration of inedible Amanitas in food containing wild mushroom was studied.
- •
Polypeptide mushroom toxins were used as adulteration markers.
- •
Phallotoxins and amanitins were measured by LC-MS/MS under ESI+ and ESI−, respectively.
- •
Basic LC gradient was used to suppress the signal of [M+Na]+ and increase that of [M+H]+ or [M−H]−.
- •
The adulterants were found in the real samples.
