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. 
Traditional uses, phytochemistry and pharmacology of genus
Many Fritillaria species have been utilized in traditional Chinese medication on account of their effects of clearing heat, moistening the lung, alleviating cough, asthma, tumours, scrofula and so on.
Chemistry and bioactivities of natural steroidal alkaloids
This review comprehensively covers the structural classification, isolation and various biological activities of 697 natural steroidal alkaloids discovered from 1926 to October 2021, with 363 references being cited.
