The cause of the decreased food intake and lower growth rate of animals fed on rye was investigated. With rats it was proved that the causative agent was soluble in petroleum ether and acetone. The growth inhibitor was identified as a mixture of 5-n-alkyl resorcinols with odd numbered side-chains of 15-23 C atoms, and of smaller amounts of 5-alkeny...
If potassium is obtained from sea-water by precipitation with calcium dipicrylamine, potassium fertilizers and sea-water will be contaminated with a little dipicrylamine. The influence of calcium dipicrylamine on metabolism of Chlorella and some other aquatic and terrestrial plants was therefore studied. It inhibited photosynthesis even at lower co...
