1. When sucrose was used at the basal carbohydrate, the rats developed dermatitis, whereas if sucrose was totally or partially substituted by “Kurozato”, “Ganmitsuto”, or cane molasses, no dermatitis resulted.
2. The concentrate of alcohol extracts of the crude sugars mentioned above cured the dermatitis occurring in the rats fed on sucrose diet and promoted growth, provided adequate amounts of vitamin B1 and flavin were fed simultaneously.
3. The data indicated that the concentrate of the crude sugars contained at least two factors essential for the nutrition of rats. One factor was adsorbed on acid clay, from which was eluted with 0.2NBa (OH)2, the other was present in the acid earth filtrate; and the former may be identical with vitamin B6 and the latter resembles the so-called filtrate factor.
