Abstract
Improved and simpler method for the quantitative determination of hippuric acid in urine for the use as a liver function test has been presented. The acid was extracted from urine three times with mixture of ether and iso-propanol respectively, and hippuric acid was determined at 230 mμ. The results agree with the crystallization method of Krause, the colorimetric method using p-dimethylaminobenzaldehyde in acetic anhydrate, as well as with our colorimetric method using benzene sulfonyl chloride. It is also indicated that the colorimetric method using benzene sulfonyl chloride may be used as a more specific method for urinary hippuric acid assay.
