Dicentra Dicentrine

Dicentrine, C20H21O4N, was first isolated from Dicentra pusilla Sieb. and Zucc. by Asahina (29) along with a small amount of protopine, although Heyl (30) had already isolated an alkaloid from D. formosa which was... [Pg.126]

Cularine, C20H23O4N, has been isolated from Dicentra cucuUaria (L.) Bernh., D. eximia (Ker-Gawl.) Torr., D. oregana Eastwood, D. formosa (Andr.) Walp., and Corydalis claviculata (L.) DC. (1, 2). Only in the last-named plant does it constitute a major constituent, but its presence in very minute amounts can be ascertained by virtue of the fact that it forms an acid oxalate which is virtually insoluble in cold water or methanol. It is, therefore, readily isolated from mother liquors from which other alkaloids have been separated either as free bases or as salts other than oxalates. It is readily extractable as its hydrochloride from aqueous solutions by means of chloroform and thus separates along with dicentrine, glaucine, bicuculline, corlumine, etc. [Pg.249]
