Alkaloids ofDicentra

Methanolic extraction ofDicentra spectabilis L., collected in the flowering period in the botanical garden of Pyatigorsk Pharmaceutical Institute, has yielded 0.17% of combined alkaloids from the epigeal part and 0.25% from the roots. By the separation of these materials, dihydrosanguinarine, sanguinarine, scoulerine, cheilanthifoline, corydine, and protopine have been obtained.Dicentra peregrina Rudolph, collected in the flowering period on the island of Sakhalin, has yielded 1.8% of combined alkaloids from the epigeal part and 1.51% from the roots. From these combined materials have been isolated isocorydine, corydine, dicentrine, protopine, dihydrosanguinarine, sanguinarine, cheilanthifoline, bicuculline, lederine, scoulerine, isoboldine, predicentrine, reticuline, and allocryptopine.Institute of the Chemistry of Plant Substances.
