Wavelength-Dependent Degradation of Ochratoxin and Citrinin by Light in Vitro and in Vivo and Its Implications on Penicillium

Toxins, 2012
It has previously been shown that the biosynthesis of the mycotoxins ochratoxin A and B and of citrinin by Penicillium is regulated by light. However, not only the biosynthesis of these mycotoxins, but also the molecules themselves are strongly affected ...

THE PHARMACOKINETICS OF OCHRATOXIN A IN RATS

Japanese Journal of Pharmacology, 1977
The absorption and tissue distribution of ochratoxin A (OCT A) following a single oral dose of OCT A were investigated in adult, male Wistar rats. In experiments concerning excretory patterns of OCT A, 14C-OCT A was used. A relatively large amount of OCT A was found in the circulating blood 48 hours after dosing.
