Direct Determination of Niacinamide in Multivitamin Preparations

Journal of Pharmaceutical Sciences, 1961
Abstract A simple method for the direct determination of niacinamide in pharmaceutical preparations is described. The method involves the reaction of niacinamide in potassium dihydrogen phosphate with cyanogen bromide and barbituric acid. The resulting purple color has a maximum absorbance at 550 m μ . Niacin does not interfere in the reaction unless

Metabolism of Niacin and Niacinamide in Perfused Rat Intestine

The Journal of Nutrition, 1979
The metabolism of [14C]nicotinic acid and [14C]nicotinamide by perfused rat intestine was studied by analyzing the 14C-products formed at various time intervals after these substrates were administered intravascularly or intralumenally. Intermediates in the Preiss-Handler pathway contained isotope when [14C]nicotinic acid was administered by either ...
