Abstract

Various analytical methods of citrinin determination are known from publications which cannot be applied without any difficulties. Low fluctuating recovery rates of standard additions, an insufficient extract purification for rye, and a rather low sensitivity based on improper HPLC conditions are being observed if the published methods are applied. An easily applicable, reliable and sensitive HPLC method in the lower ppb range on the basis of a solid phase extraction combined with a HPLC gradient which allows for a sensitive fluorescence detection, is under development. The results already achieved are described in the following.
