Summary

1. A study of the dynamics of the accumulation of the alkaloids ofD. strictus according to the vegetation period showed the maximum accumulation of alkaloids in the period before budding with 0.2% in the epigeal part and 0.72% in the roots, and in the period of full fruit-bearing with 0.05–0.3% of combined alkaloids in the seeds.

2. The separation of a mixture of bases of the epigeal part and of the seeds yielded seven alkaloids, six of which contained sulfur: diphthocarpamine, diphthocarpidine, diphthocarpaine, diphthocarpamidine, dipthocarpine, diphthocarpinine, and base No. 5.

3. A study of the chemical properties and spectral characteristics of diphthocarpamidine has shown that it is N,N′-diisopropylurea, and we are the first to have isolated it from a plant.
