Alkaloids ofCorydalis paniculigera


The alkaloid composition of the roots ofCorydalis paniculigera Rgl., collected in the flowering phase in the Alai range, has been studied. Chloroform extraction yielded 0.39% of total alkaloids, from which were isolated wilsonirine, thalicmidine, coclaurine, stylopine, dihydrosanguinarine, sanguinarine, oxosanguinarine, adlumine, adlumidine, bicucculine, sibiricine, protopine, pancorine, and corunnine, and new alkaloids which have been called pancoridine (I) and pancorinine (II). The structures of (I) and (II) have been established on the basis of spectral characteristics and also the production of wilsonirine on their reduction in sulfuric acid.
