Metal complexes involving pyridoxine and pyridoxamine
… Cu(II), Ni(II), Co(III), Cd(II) and Zn(II), and pyridoxamine in various protonated forms. Infrared spectra provide evidence for protonation at the pyridine nitrogen site in the complexes, but not in the neutral vitamins and the complexes of anionic pyridoxamine. Thus the complexed vitamins are in …

Palladium and platinum complexes of vitamin Bâ
Palladium and platinum complexes of pyridoxamine, pyridoxine and pyridoxal have been prepared. The structures of the complexes PtCI2PM.H20, trans-PdC12 (PN)2 and [PLH+ ]2[PtC16] 2- ,H20 have been determined by use of single crystal x-ray studies. The compounds PdC12PH, trans-PdC12 (PN) 2 , …

Liquid chromatographic separation and quantitation of B-6 vitamers in rat liver, kidney, and brain tissues
… vitamers pyridoxal (PL), pyridoxine CPN), and pyridoxamine (PM) as well as the internal standard deoxypyridoxine. An extraction procedure, compatible with the HPLC system, was developed to isolate the B-6 vitamers from rat livers, kidneys, and brains. PL values were derived from the sum of …

Vitamin B-6 status of a group of female adolescents: E-ALAT, microbiological, and HPLC methods
… the criterion. The plasma pyridoxal, pyridoxine, pyridoxamine and total B-6 vitamer concentrations of subjects having inadequate E-ALAT values were lower, generally significantly, than those of girls with adequate levels. In the subjects with adequate status, the vitamer found in the largest …

Comparison of high performance liquid chromatographic, gas liquid chromatographic, and Saccharomyces uvarum methods for the determination of B{u2086} compounds
… separate the B₆ compounds pyridoxol, pyridoxal, pyridoxamine, and 4'-deoxypyridoxine. A gas chromatography (GC) equipped with a ⁶³Ni electron capture (EC) detector was used to separate the N-methyl-bis-trif luoroacetamide derivatives of the B₆ compounds on a l.54m x 2mm i.d. glass column packed …

Influence of vitamin B-6 intake on vitamin B-6 status of lactating women and on the vitamin content of their milk: enzymatic, microbiological, and HPLC techniques
… than in the nonsupplemented group. Pyridoxal, pyridoxamine, pyridoxine, and total vitamin B-6 concentrations in milk were higher, sometimes significantly, in the supplemented than in the unsupplemented group as determined by microbiological assay and HPLC. There were significant correlations …
