This paper describes a HPLC method with DAD detection for determining a mixture of four trichotecenes B in wheat protected by fungicides. The recoveries of trichotecenes B from wheat treated at two levels of fortification: 0.2 and 0.6 mg/kg for NIV, DON, 15-AcDON and 3-AcDON were: 101.83; 75.78; 84.58; 75.19 and 71.17; 70.24; 87.83; 74.95, respectively. The results confirmed usefulness of this method as easy for determining trichotecenes B in plant material.
