Fourteen previously undescribed steroidal alkaloids, including six jervine-type, wabujervine A-E and wabujerside A, seven cevanine-type, wabucevanine A-G, and one secolanidin-type, wabusesolanine A, along with thirteen known steroidal alkaloids, were isolated from the bulbs of Fritillaria unibracteata var. wabuensis. On the basis of comprehensive analysis of IR, HRESIMS, 1D and 2D NMR spectroscopic data, and single-crystal X-ray diffraction analyses, their structures were elucidated. In the zebrafish acute inflammatory models, nine compounds showed anti-inflammatory activity.
