摘要
To investigate the chemical constituents of the bulbs of Fritillaria wabuensia.Chromatography techniques were used to isolate the chemical constituents. EI-MS, 1HNMR, 13 CNMR and DEPT were used to determine the structures of the isolated constituents.Three alkaloids were isolated from the bulbs of Fritillaria wabuensia, and were identified as imperialine (I), imperialine-beta-N-oxside (II), isoverticine-beta-N-oxide (III).Isoverticine-beta-N-oxide was isolated from the bulbs of Fritillaria wabuensia for the first time. Isoverticine-beta-N-oxide is a new alkaloid.
