“…AOH, AME and TeA were frequently detected in apples, apple products, apple juice concentrates, mandarins, olives, pepper, red pepper, tomatoes, tomato products, oilseed rape meal, sunflower seeds, sorghum, wheat (as cited by Scott, 2001) and edible oils (olive oil, rapeseed oil, sesame oil, sunflower oil) (Kocher 2007). AOH and AME were detected in prune nectar, raspberries, red currant, barley, oats (as cited by Scott, 2001), Japanese pears (Tirokata et al, 1969), citrus fruit (Magnani et al, 2007) and carrots (Solfrizzo et al, 2004(Solfrizzo et al, , 2005.

“…More than 30 potentially toxic products have been isolated from Alternaria species. Alternaria species produce many secondary metabolites, mycotoxins and mostly hostspecific or non-host specific phytotoxins, which play an important role in the pathogenesis of plants (Templeton et al, 1967;Pero and Main, 1969;Tirokata et al, 1969, Coombe et al, 1970Pero et al, 1973a;Ueno et al, 1975;Janardhanan and Husein, 1975;Maekawa et al, 1984;Rizk et al, 1985;Tadakazu et al, 1985;Liebermann et al, 1988;Visconti et al, 1988;Logrieco et al, 1990;Thomma, 2003).…”

Microfungi of the genus Alternaria are ubiquitous pathogens and saprophytes. Many species of the genus Alternaria commonly cause spoilage of various food crops in the field or post-harvest decay. Due to their growth even at low temperatures, they are also responsible for spoilage of these commodities during refrigerated transport and storage. Several Alternaria species are known producers of toxic secondary metabolites - Alternaria mycotoxins. A. alternata produces a number of mycotoxins, including alternariol, alternariol monomethyl ether, altenuene, altertoxins I, II, III, tenuazonic acid and other less toxic metabolites. Tenuazonic acid is toxic to several animal species, e.g. mice, chicken, dogs. Alternariol, alternariol monomethyl ether, altenuene and altertoxin I are not very acutely toxic. There are several reports on the mutagenicity and genotoxicity of alternariol, and alternariol monomethyl ether. Alternariol has been identified as a topoisomerase I and II poison which might contribute to the impairment of DNA integrity in human colon carcinoma cells. Analytical methods to determine Alternaria toxins are largely based on procedures, involving cleanup by solvent partitioning or solid phase extraction, followed by chromatographic separation techniques, in combination with ultraviolet, fluorescence, electrochemical and mass spectroscopic detection. A large number of Alternaria metabolites has been reported to occur naturally in food commodities (e.g. fruit, vegetables, cereals and oil plants). Alternariol, alternariol monomethyl ether and tenuazonic acid were frequently detected in apples, apple products, mandarins, olives, pepper, red pepper, tomatoes, tomato products, oilseed rape meal, sunflower seeds, sorghum, wheat and edible oils. Alternariol and alternariol monomethyl ether were detected in citrus fruit, Japanese pears, prune nectar, raspberries, red currant, carrots, barley and oats. Alternariol monomethyl ether and tenuazonic acid were detected in melon. Natural occurrence of alternariol has been reported in apple juice, cranberry juice, grape juice, prune nectar, raspberry juice, red wine and lentils.

Embora a toxicidade aguda em animais seja moderada, AOH e AME são mutagênicos in vitro e também há evidência de propriedades carcinogênicas em ensaios não convencionais, utilizando o locus do gene hipoxantina-guanina fosforibosiltransferase (HPRT) em células V79 e o locus do gene da timidina quinase (TK) em células L5178Y de linfoma de camundongo (BRUGGER et al, 2006;EFSA, 2011;OSTRY, 2008).…”
