title: Determination of N1-methylnicotinamide by HPLC postcolumn photoirradiation.
abstract: A method for the determination of N1-Methylnicotinamide (NMNA) was developed by the fluorescence formed by UV irradiation after separation by HPLC with a mobile phase containing hydrogen peroxide and 18-crown-6. This method was applied to human urine and serum.
