Two new alkaloids, 6α/6β-hydroxy-3-O-methylepimaritidine (3-epipapyramine) (4 and 5) were isolated from the bulbs of Narcissus tazetta L. var. chinensis Roem. together with four known alkaloids, maritidine, 3-O-methylmaritidine, epigalanthamine and lycoramine. The structures of 4 and 5 were determined on the basis of their IR, UV, CD, 1H-NMR and MS fragments.
