A Study of the Vitamin B Complex* of Red Kidney Beans and Polished Rice,{dagger}

J. H. Axtmayer

(From the Department of Chemistry, University of Porto Rico, Rio Piedras)

Experiments are described whereby the limiting factors of the vitamin B complex in red kidney beans and polished rice have been found.

The polished rice was found to be deficient in both factors of the vitamin B complex.

Vitamin G was found to be the limiting factor of the vitamin B complex of red kidney beans which are therefore relatively richer in vitamin B(B1) than in vitamin G(B2).

The vitamin B deficiency of the polished rice which was used in these experiments is not made good by feeding the rice with red kidney beans, for the former was deficient in both factors while the latter was poor in vitamin G.


* The term "vitamin B complex" is used in this paper to signify the combination of the thermo-labile factor, vitamin B (B1) and the thermo-stable factor, vitamin G (B2).
