Two new 2, 5-dihydrofuryl-γ-lactam derivatives, fulvanine D and E have been extracted from Hemerocallis fulva L. var. kwanso REGEL along with fulvanine A, B and C. The structures of fulvanine D and E have been established as 1-(3-hydroxymethyl-2, 5-dihydro-2-furyl)azacyclopenta-3-hydroxy-5-methoxy-2-one (1) and 1, 2, 4, 5, 5a, 6, 7, 8, -8a, 8b-decahydro-1, 5-dioxa-8a-aza-asym-indacen-7-hydroxy-8-one (2).
