摘要
A new C-nor-D-homo-steroidal alkaloid named taipaienine, together with five known alkaloids namely chuanbeinone, imperialine, verticinone, perimissine and isoverticine were isolated from the bulbs of Fritillaria taipaiensis L. var. ningxiaensis Y. et W.. The unusual structure of taipaienine was a first sample with a hydroxyl group substituted at C-25 of (22)R-trans quinolizidine moiety with orientation of nitrogen lone pair. Their structures were determined by various spectral analyses.
