title: Steroidal alkaloids of Fritillaria maximowiczii.
abstract: From the bulbs of Fritillaria maximowiczii, in addition to the known jerveratrin alkaloid, kuroyurinidine, three new steroidal alkaloids, 23-isokuroyurinidine, 15,16-seco-22 alpha H, 25 beta H-solanida-5,14-dien-3 beta-ol O-beta-D-glucopyranosyl-(1-->4)-beta-D-xylopyranoside and hapepunine 3-O-beta-cellobioside have been isolated and structurally elucidated.
