Berberis alkaloids.hoop. Berberis heteropoda Schrenk alkaloids study

The alkaloid composition of young shoots and leaves of B. heteropoda has been studied. Along with the known alkaloids, two new N alkaloids, methyldihydroberberine and 8-oxoberberubine, were isolated, the structures of which were established by means of chemical transformations and the study of spectral properties. Of the known alkaloids, berbamunin, aromoline, glaucine, talikmidin, isocoridin, and reticulin were first found in plant B.heteropoda. Pseudopalmatine and laudanosine were first found in plants of the genus Verberis
