Pancratium canariense as an Important Source of Amaryllidaceae Alkaloids

Four new alkaloids (1−4) have been isolated from a methanolic extract of bulbs of Pancratium canariense, together with 12 known alkaloids (5−16). The structures of the new alkaloids were determined by extensive 1D and 2D NMR spectroscopic studies and X-ray diffraction.
