A simple and highly sensitive high-performance liquid chromatographic (HPLC) method for the determination of alpha-keto acids in human serum and urine is described. In an acidic solution, twelve species of alpha-keto acids examined were converted by reaction with 1,2-diamino-4,5-methylenedioxy-benzene into
