The constituents of bulb of F. puqiensis were studied. Five steroid alkaloids were isolated. The plane structure and stereoscopic configuration of 4 compounds were elucidated. They are named as puqienine A (FP-33), puqienine B (FP-3), N-demethyl-puqietinone (〓 FP-34) and puqietinone (〓, FP-9). Puqienine A and N-demethyl-puqietinone are new compounds. Puqienine B is as same as FPQ-3 elucidated by Prof.
