Abstract
1. Chicken, young rats, and pregnant rats and their weanlings have been fed on the rations containing a large quantity of the powder of red discolored wheat. There were no effects on the growth, distribution of viscera organs and pregnancy of animals.
2. An alcoholic extract of the red discolored wheat has been prepared and given to young rats in amount equivalent to about 25 grams of the red discolored wheat, per head. In this case, the growth of rats has been depleted and the content of non protein nitrogen in their livers has increased.
3. The alcoholic extract has been separated into ether soluble and insoluble fractions. The former fraction has shown the same maximum absorbance and peroxide values compared to the same preparation from normal wheat, except for the carotenoids which were absent in the preparation from discolored wheat.
4. The content of histamine in the ether insoluble fraction was very little.
5. Black discolored barleys contained higher amount of amide and reducing sugar.
