Vitamin B6 is the mass fraction of the sum of pyridoxine,pyridoxal, pyridoxamine including their phosphorylated derivatives determined as pyridoxine. The β-glycosylated forms are not taken into account. These can be determined with the method given in EN 14663[1] by which the different vitamers of vitamin B6 (pyridoxal, pyridoxamine and pyridoxine) are separated andindividually quantified. A third European Standard (EN 141661) [2] determines the total vitamin B6 bymicrobiological assay.【中国标准分类号】: X04【国际标准分类号】: 67_050【页数】: 19P.;A4【正文语种】: 德语
