Abstract
The measurement of urinary orotidine, uridine and thymine which are intermediates in pyrimidine biosynthesis, is important for screening and diag-nosis inborn ergors of metabolism, such as urea cyclel and pyrimidine metabo-lism disorders 2 , as well as the measurement of urinary orotic acid and uracil l,3. Several high-performance liquid chromatography (HPLC) methods have been reported by a number of researchers. However, these HPLC methods for uridine and thymine analysis require rather complicated sample preparation in order to obtain accurate results 1. Although, a simple method for measuring orotidine and orotic acid were recently reported 4, it is not capable of evaluating near-normal levels of orotidine.
