Title: Steroidal alkaloids from the bulbs of Fritillaria puqiensis.

Authors: Jiang Y, Li H, Li P, Cai Z, Ye W.

Abstract: Four new steroidal alkaloids, puqienine A (1), puqienine B (2), N-demethylpuqietinone (3), and puqietinonoside (4), along with a known steroidal alkaloid, puqietinone, were isolated from the bulbs of Fritillaria puqiensis. The structures of these compounds were elucidated on the basis of spectroscopic analysis. The compounds exhibited significant antitussive activity on ammonia liquor-induced cough in mice. Furthermore, the compounds were evaluated for activities against A549 human lung carcinoma cell line, BGC-823 human stomach adenocarcinoma cell line, SMMC-7721 human hepatocarcinoma cell line, and HL-60 human promyelocytic leukemia cell line.
