Patulin
Patulin is found in pomes. Mycotoxin, found as a contaminant of foods, e.g. apple juice. Sometimes detd. in apple juice Patulin is a mycotoxin produced by a variety of molds, particularly Aspergillus and Penicillium. It is commonly found in rotting apples, and the amount of patulin in apple products is generally viewed as a measure of the quality of the apples used in production. It is not a particularly potent toxin, but a number of studies have shown that it is genotoxic, which has led to some theories that it may be a carcinogen, though animal studies have remained inconclusive. Patulin is also an antibiotic. Several countries have instituted patulin restrictions in apple products. The World Health Organization recommends a maximum concentration of 50 µg/L in apple juice Mycotoxin, found as a contaminant of foods, e.g. apple juice. Sometimes detd. in apple juice D009676 - Noxae > D011042 - Poisons > D009183 - Mycotoxins D009676 - Noxae > D009153 - Mutagens Patulin (Terinin) is a mycotoxin produced by fungi including the Aspergillus, Penicillium, and Byssochlamys species, is suspected to be clastogenic, mutagenic, teratogenic and cytotoxic. Patulin induces autophagy-dependent apoptosis through lysosomal-mitochondrial axis, and causes DNA damage[1][2][3][4].

(E)-ascladiol
A butenolide that is furan-2(5H)-one which is substituted by a hydroxymethyl group at position 4 and a 2-hydroxyethylidene group at position 5 (the 5E isomer). A direct precursor of patulin in cell-free preparations of Penicillium urticae patulin-minus mutants J1 and S11, but not S15.
