Ochrobirine has been identified among the alkaloids of Corydalis vaginans The isolation of fumariline from Fumaria indica has been reported.The new alkaloids yenhusomine (181) and yenhusomidine (182) have been isolated, along with ochotensimine, from Corydalis ochotensis. The isolation and properties of the alkaloid corydalispirone [hypecorinine (117)] are discussed in Section 10. 

Berberine, coptisine, and /3-stylopine methohydroxide have been isolated from Papaver rhoeas L., berberine, berberubine, isocorypalmine, and thalifendine from Thalictrum dioicum, berberine from T. sachalinense, corydaline from Corydalis marschalliana, scoulerine, ophiocarpine, isocorypalmine, and cheilanthifoline from C. vaginans, C. gigantea, and C marschalliana, and ophiocarpine, stylopine, cheilanthifoline, isocorypalmine, and the chlorides of berberine, coptisine, and dehydrocheilanthifoline from C. ophiocarpa. The alkaloids of C. ophiocarpa were separated by droplet counter-current chromatography. ... 

Protopine and allocryptopine have been isolated from Papaver rhoeas, and protopine from Corydalis caua," C. gigantea, C. marschalliana, C. remota, C. rosea, and C. vaginans. The effect of protopine on induced cardiac arrhythmias has been studied." ...
