Isolation of N-Demethylgalanthamine from the Bulbs of Crinum asiaticum L. var. japanicum BAKER (Amaryllidaceae)

Abstract

The bulbs of Crinum asiaticum L. var. japonicum BAKER (Amaryllidaceae) were found to contain N-demethylgalanthamine (II) as well as lycorine (III) and crinamine (IV). This is the first time that II has been isolated directly, as an single base, from a member of the Amaryllidaceae.
