Ingia / Ingia

A new alkaloid, N-allylnorgalanthamine ( 1), was isolated from the bulbs of LYCORIS GUANGXIENSIS Y. Hsu et Q. J. Fan (Amaryllidaceae). Additionally, seven known alkaloids, lycorine, narwedine, galanthamine, lycoramine, crinine, norgalanthamine, and pseudolycorine were also obtained. The structure of

Ingia / Ingia

The Amaryllidaceae are widely distributed medical plants. Lycorine, lycoramine, lycoremine, and lycobetaine are the major active alkaloids in Amaryllidaceae plants. A nonaqueous CE ESI-IT-MS method for separation, identification, and quantification of the Amaryllidaceae alkaloids has been developed.
