Anaphylaxis to riboflavin (vitamin B2)
Annals of Allergy, Asthma & Immunology, 2001Vitamin supplements are used more commonly in normal healthy subjects than in patients with vitamin deficiency. Thiamine (vitamin B,) is the vitamin that most frequently induces allergic reactions. To the best of our knowledge, no case of anaphylaxis to riboflavin (vitamin B2) has thus far been reported in the literature.We describe a previously ...

Wie wir bereits bei der Besprechung des Vitamin B-Komplexes gesehen haben, konnten im Jahre 1926 Goldberger und Mitarbeiter (1) zeigen, das das Vitamin B aus zwei verschiedenen Faktoren bestand, dem antineuritischen Faktor und einem zweiten Faktor, der von Goldberger und Mitarbeitern (1) als identisch mit dem Antipellagrafaktor des Menschen angenommen ...

A CHEMICAL study of vitamin B2 in a cold aqueous extract of commercial liver extract (Eli Lilly, No. 343) has been made. This solution is very rich in vitamin B2, being effective in producing good growth in young rats on a B2 deficient diet, in a daily dose representing 40–60 mgm. of the original liver extract.

Vitamin B2 and Vitamin E In Long-Term Hemodialysis
JAMA: The Journal of the American Medical Association, 1971To the Editor. — Various metabolites of proteins, vitamins, and drugs are excreted by the kidney or intestines. Vitamin B 2 and its metabolites are usually excreted by the former and vitamin E by the latter route. Patients receiving maintenance hemodialysis are usually anuric or oliguric, and vitamin B 2 is automatically removed by the hemodialysis ...

Untersuchungen über Vitamin B2
Klinische Wochenschrift, 1935B2-Mangel bewirkt keine makrocytare perniciosaahnliche Anamie bei der Ratte. B2 wurde in Kuhmilch, Ziegenmilch, Muttermilch nachgewiesen und quantitativ verglichen. Von Leberextrakten enthalt Hepracton kein, Campolon reichlich B2. Die Befunde sprechen gegen eine Identitat von exogenem Perniciosafaktor und Vitamin B2.

Vitamin B2 is an isoalloxazine derivative with a ribitol side chain (Figure 28). It is an orange yellow crystalline compound, sparingly soluble in water, heat stable at normal temperatures, but unstable in alkali solution and on exposure to ultraviolet light.

Nutritional glossitis and vitamin B2 therapy
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1942Abstract The successful treatment of six cases of superficial glossitis with synthetic riboflavin is described. The aetiology of nutritional glossitis as ascertainable by therapeutic tests is discussed. Recent analyses reveal that spinach is a rich source of riboflavin.

, 2007 Biosynthesis of Vitamin B2 and Flavocoenzymes in Plants
2011Abstract Riboflavin (vitamin B 2 ) derivatives serve as cofactors for a very wide variety of redox enzymes but are now also known to participate in the catalysis of certain non-redox reactions and as cofactors of blue-light photoreceptors. In parallel with the unique features of its chemical reactivity, the vitamin is biosynthesised from one molecule

PERHAPS it is useful to direct attention to the above subject before confusion gets worse confounded. It was pointed out in 1931 that the use of the terms vitamin B2 and anti-dermatitis (anti-pellagra?) factor interchangeably was already causing difficulties1. The discovery by Kuhn and his co-workers that lactofiavine is able to supplement a vitamin B2-
