Dear Longvah,
I gather that it is the single vitamers, pyridoxine, pyridoxal, pyridoxamine and their phosphate esters/glucosides, you want information on and not (total) vitamin B6?
Traditionally, the (total) vitamin B6 was determined using a microbiological assay (Saccharomyces cerevisiae/carlsbergensis/uvarum a.o.), and I think that a substantial part of the vitamin B6 values in food composition databases/tables have been determined with this method – at least in the databases that I am familiar with..
Here and now, I am not aware of a database/table that splits the vitamin B6 up in its vitamers.
However, a Google Scholar search reveals quite many scientific papers, especially on the methods but also content of the B6 vitamers in food (actually quite a few old papers), so I think that you may have to go the “hard way” and go through the literature.
On methods from the most recent Vitamin Conference: www.foodandnutritionresearch.net/index.php/fnr/article/download/5409/21327, and on content in foods, I stumbled over several papers written by Polansky and Toepfer in the late 1960’s, e.g. http://www.aaccnet.org/publications/cc/backissues/1969/Documents/Chem46_664.pdf.
Similar papers by Polansky et al. are
Vitamin B6 components in fruits and nuts (Journal of the American Dietetic Association, 1966, Vol.48(2), pp.109-11)
Vitamin B6 components in fresh and dried vegetables (Journal of the American Dietetic Association, 1969, Vol.54(2), pp.118-21)
Vitamin B6 components in some meats, fish, dairy products, and commercial infant formulas (Journal of Agricultural and Food Chemistry, 1969, Vol.17(6), pp.1394-1397)
I know that the papers are “old”, but is a starting point.
Wageningen UR Library has a nice global search function (see http://www.wageningenur.nl/en/expertise-services/Facilities/library.htm). A search with “pyridoxine pyridoxal pyridoxamine food” gives 807 hits. It is another good way to get a “brief” overview.
I hope that this gives you a starting point for your further investigations.
All the best,
Anders

Dear All,
I am looking for data on the content of vitamin B 6 vitamers (pyridoxine, pyridoxal & pyridoxamine) content in foods. Does anyone have any idea where I can find such data?
Best wishes
Longvah
