In our studies on the biosynthesis of vitamin B6 in yeast (2), we are confronted with the problem of a fairly rapid assay of the different forms (known and unknown) of this nutrient that are excreted into the culture medium. The existing assay procedures for vitamin B6 are subject to at least one of several restrictions. They are time consuming, incapable of distinguishing between the three forms of the vitamin (pyridoxol, pyridoxal, and pyridoxamine), or preclude the regeneration and reisolation of the material after analysis.
