Abstract
A modification of the thiochrome method for the fluorimetric detn. of vit. B1 in urine in the presence of nicotinamide methochloride is described. Since treatment of the isobutanol extract with HC1 removes the thiochrome fluorescence, the difference between readings taken before and after this treatment is a measure of the vit. B1 content of the urine.This publication has 2 references indexed in Scilit:
