it was established that gradual formation of the alkaloid complex takes place in parallel with growth differentiation of the organs during seed germination and the formation of seedlings , which is due to the de novo biosynthesis ( in a specific sequence ) of alkaloids of various structural types : first 1,2,9,10-substituted aporphines , then protopines , and , finally 1,2,10,11-substituted aporphines , benzophenanthridine , as well as morphinans .
