Radioimmunochemical detection (RIA) following fractionation of urine extracts via high performance liquid chromatography (HPLC) turned out to be a very specific method for the identification of stilbene derivatives in bovine urine. Combination of the high resolution of the HPLC with a specific RIA is a suitable method to discriminate between the presence of different stilbene derivatives like diethylstilboestrol (DES), dienoestrol (DE) and hexoestrol (HEX) or other unknown compounds interfering in the celite-RIA used in the screening. Using this screening method 8200 samples of bovine urine were investigated on the presence of stilbene derivatives of which 133 were classified as 'positive'. In 106 'positive' urines the presence of DES was shown and in 19 'positive' urines the presence of DE or HEX, using the method described in this report whereas in 8 'positive' urines an unknown immunochemical active compound was detected. During 1.5 year of comparative investigation no qualitative discrepancies occurred between the results of the HPLC-immunogram procedure and the final confirmation by high resolution gas chromatography-mass spectometry (GCMS).
