The additivityrelation in values of split CDcurves previously established with pyranose p-bromobenzoates was shown to be valid for p-bromobenzoates of the cage-like trichothecene system (which also possesses a primary hydroxyl group). This suggests that additivity is generally valid even for congested multichromophoric molecules. The relation has been integrated Into a new micro method for trichothecene

The first stable isotope dilution assay (SIDA) for the simultaneous quantitation of the most abundant type A trichothecenes in foods and feeds was developed. Synthesis of carbon-13-labeled T2-toxin, HT2-toxin, diacetoxyscirpenol, and monoacetoxyscirpenol was accomplished by [13C2]-acetylation of T2-triol and scirpentriol, respectively. Scirpentriol was prepared from diacetoxyscirpenol by complete alkaline
