“…McFarlane noted the similarity of the absorption spectra of aqueous cobalt(II) nitrate solutions and [Fe(bpy) 3 ] 2+ and proposed the former as a colorimetric standard for calibration [279]. This colorimetric method rapidly became the method of choice for the analysis of iron in a wide range of materials and the technique was applied, inter alia, to the determination of the iron content of hematin and cytochrome c [286], water [287,288,289,290], milk [291], beer [292,293], other foodstuffs [294,295,296,297,298,299,300,301], soil and minerals [302,303,304,305,306], teeth [307,308], blood [285,309,310,311,312,313,314] and other biological materials [315,316,317,318,319] and homeopathic formulations [320]. It was recognized that the methods using bpy for the determination of iron gave a measure of the "available" iron, and any Fe that was strongly bound in heme proteins or ferritin would not necessarily be included in the total iron [321,322].…”

The Early Years of 2,2′-Bipyridine—A Ligand in Its Own Lifetime

The first fifty years of the chemistry of 2,2′-bipyridine are reviewed from its first discovery in 1888 to the outbreak of the second global conflict in 1939. The coordination chemistry and analytical applications are described and placed in the context of the increasingly sophisticated methods of characterization which became available to the chemist in this time period. Many of the “simple” complexes of 2,2′-bipyridine reported in the early literature have been subsequently shown to have more complex structures.

“…The rate of haemoglobin regeneration is then taken as an indication of the relative effectiveness of that particular dietary source of iron as compared with the regeneration when a solution of an iron salt is fed. This method has also been used with success by several other workers (Kletzien, 1938;Underwood, 1938;Lucas & Summerfeldt, 1939;Harris, Mosher & Bunker, 1939;Freeman & Burrill, 1945;Miller & Louis, 1945) and has several advantages over the previously mentioned methods. As the rats are only about 6 weeks old at the beginning of the experimental period, and in a highly anaemic condition, they will require iron both for recovery and for the production of the additional haemoglobin occasioned by increases in body weight.…”

“…Such iron, it was claimed, was available to the animal and could be estimated by means of the reagent aa'-dipyridyl. While several investigators (Elvehjem et al 1933;Sherman et al 1934a, 6;Smith & Otis, 1937a;Harris et al 1939;Widdowson & McCance, 1944) have claimed that the method gives good agreement with results obtained by means of a bioassay, there is an equally strong body of opinion (Myers, Remp & Bing, 1935;Ascham et al 1938;Hahn & Whipple, 1938;Miller & Louis, 1945) that results obtained by this method show very poor agreement with those obtained by means of a bioassay. As availability denned in this way has little physiological significance, the procedure has accordingly fallen into disrepute.…”

1. The availability of iron in three species of grass has been investigated using the rat as the experimental animal.2. Two procedures, namely, the increase in blood haemoglobin concentration, and the gain in total gramme of haemoglobin by nutritionally anaemic rats were employed.3. Inorganic iron, as ferric chloride, was shown to be significantly more available than the iron contained in the three grasses.4. The iron in the grass timothy was found to be significantly more available than that in ryegrass or cocksfoot.5. Possible reasons for the differences in iron availability were discussed.

“…(Xia et al, 2016). Bioavailability of iron available in molasses is around 85% of the total iron (Harris et al, 1939). It has been widely advertised for its therapeutic properties believed to be a result of its rich mineral content (Wang et al, 2011).It is considered to be generally regarded as safe by the U.S. Food and Drug Administration and a rich source of phenolic compounds (Guimarães et al, 2007).…”
