[Investigations on the production of mycotoxins and their quantitative analysis. VI. Citreoviridin (author's transl)].

UV-densitometric and fluorodensitometric evaluations of the mycotoxin citreoviridin on thin-layer plates are described. The UV maximum is at 360 nm on thin-layer plates and at 388 nm in ethanolic solution. Its emission maximum has been found to be at 525 nm both in chloroform and on thin-layer plates. The two procedures are similar in their sensitivity. Since the UV-densitometric evaluation is more reliable, it is preferred to fluorodensitometric procedure.
