Abstract
The secondary metabolites produced by genus Alternaria; dibenzo-α-pyrone derivatives alternariol (AOH), alternariol monomethyl ether(AME), and altenuene (ALT), tetramic acid derivative tenuazonic acid (TeA), perylene derivatives altertoxin-I (ATX-I) and relative compounds (altertoxin II and III) were known as Alternaria mycotoxins. Alternaria mycotoxins have been detected in crops and fruits harvested in field affected with Alternaria and also their products including apple juice and tomato products. The metabolites had the toxicity to mammalian cell, bacteria and experimental animals. Alternaria may become a potential biohazard of the Alternaria to humans and animals concerning mycotoxicosis. Alternaria had been isolated frequently from atmosphere, therefore the risk of human and animal health evoked by Alternaria exposure could be came high.
