A novel (22S,25R)-13,17-didehydro-5α-cevanine alkaloid, ebeienine (1), was isolated from trhe bulbs of Fritillaria ebeiensis var. purpurea, together with (25S)-20-deoxy-5α-cevanin-3β,6β-diol (ebeiedine (2)), and (25S)-20-deoxy-5α-cevanin-3α-ol-6-one (ebeiedinone (3)).Their structures were elucidated by physical methods and finally confirmed by X-ray crystal structure detrmination.Keywords - Fritillaria; traditional Chinese medicine; 13,17-didehydrocevanine alkaloid; 20-deoxy-5α-cevanine alkaloid; D/E trans-5α-cevanine alkaloid
