Forms of vitamin B6 in human milk.
A previously developed high performance chromatographic method has been modified slightly and used to determine the forms of vitamin B6 in human milk. The chromatographic traces are free of compounds that would interfere with the two principal forms found, pyridoxal and pyridoxal phosphate. The method is fast and reliable; it yields recoveries of from 90 to 106% for the vitamers and agrees with results obtained on the same samples with the standard microbiological assay.
