Alternaria mycotoxins in weathered wheat from China.

Twenty-two samples of weathered wheat kernels from the 1998 crop, representing three locations in the suburbs of Beijing, China, were examined for the presence of Alternaria toxins. Wheat kernels were significantly invaded by Alternaria species, mostly A. alternata, with an average infection frequency of 87.3%. Alternariol was  detected in 20/22 samples at concentrations ranging between 116 and 731 mg/kg and alternariol methyl ether was detected in 21/22 samples at concentrations ranging between 52 and 1426 mg/kg. Tenuazonic acid was detected in all samples  analysed at an average concentration of 2419 mg/kg with a maximum of 6432 mg/kg. All samples were free from altertoxin 1 and altenuene, This is the first report of the natural occurrence of alternaria toxins in Chinese wheat.
