Xanthurenic Acid Dehydroxylation by Fecal Microflora

Experimental Biology and Medicine, 1965
SummaryIn vitro dehydroxylation of xanthurenic acid has been demonstrated in an artificial cecum charged with rabbit fecal fluid. The dehydroxylated product, 8-hy-droxyquinaldic acid, was isolated and crystallized. The results clearly indicate that intestinal microorganisms are responsible for the dehydroxylation reaction.

Improved fluorometric quantification of urinary xanthurenic acid [PDF]

Clinical Chemistry, 1996
Abstract Measurement of urinary xanthurenic acid (XA) has been used clinically to study a variety of disorders caused by vitamin B6 deficiency. To obviate some cumbersome steps of current methods for measuring XA in human urine, we have developed a simple fluorometric method.
