Abstract

Two new alkaloids, demethylmaritidine (4) and (-) -N-demethyllycoramine (5), were isolated from the bulbs of Hymenocallis rotata HERB. (Amaryllidaceae) together with eleven known bases, vittatine (6), alkaloid-13 (7), 3-epimacronine (8), ismine (9), pretazettine (10), lycoramine (11), lycorine (12), tazettine (13), haemanthamine (14), galanthamine (15), and N-demethylgalanthamine (16).
