A new alkaloid from Fritillaria ussuriensis Maxim.
Pingbeimunone A (1), a new compound, together with the known ussuriedine (2), benzo[7,8]fluoreno[2,1-b]quinolizine cevane-3,6,16,20-tetrol (3), ebeiedinone (4), pingbeimine C (5) and verticine (6) were isolated from Fritillaria ussuriensis. The structure was elucidated on the basis of spectral analysis (IR, NMR and MS spectroscopy). In addition, their AChE inhibitory activities were also tested.
