Abstract
Reports from recent conferences on vitamin B-6 metabolism indicate that it would be most useful to identify and quantitate all forms of vitamin B-6 in animal tissue and physiological fluids (1,2). Enzyme or microbiological assays by themselves do not yield information on the individual species, but chemical assays, particularly those involving high performance liquid chromatography (HPLC), do have this potential (3,4). The problem with chemical assays is that a suitable extraction procedure must be found which quantitatively extracts the compound(s) of interest from complex samples, prevents decomposition or metabolism during the extraction, and is compatible with the analytical HPLC systems.
