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 1 was established through the interpretation of spectral data.
