High Pressure Liquid Chromatography of Zearalenone in Cereals
Journal of AOAC INTERNATIONAL, 1978 Abstract A high pressure liquid chromatographic method has been developed for determining zearalenone in cereals. The sample is extracted with phosphoric acid and chloroform. The extract is cleaned up by washing on a silica gel column with benzene-hexane or cyclohexaneethylene dichloride-ethyl ether and eluting with chloroform, and ...
