## Abstract A new, sensitive method for the determination of oncopterin, biopterin, and neopterin in human urine has been developed using SPE with 6,7βdimethylpterin as internal standard and gradient HPLC with fluorescence detection. SPE was tested for the preβtreatment of urine samples on differen
