[Determination of trichothecenes in cereals].

A simple method is described of identification and determination of deoxynivalenol (DON), nivalenol (NIV), diacetoxyscirpenol (DAS) and T-2 toxin in cereals. Chloroform-ethanol extracts were purified in columns filled with active charcoal, aluminium oxide and celite and were analysed by the method of thin-layer chromatography. The results were evaluated exposing fluorescent trichothecene derivatives to ultraviolet light, after they had been obtained on a chromatographic plate with aluminium chloride and sulphuric acid. The detectability of the method for various toxins was: DON--37, NIV--100, DAS--50, and T-2 toxin--100 mcg/kg.
