title: [Studies on chemical constituents of Fritillaria thunbergii Miq].
abstract: A new C-nor-D-homosteroidal alkaloid was isolated from the bulbs of Fritillaria thunbergii Miq. with peimine (I) and peiminine (II), named zhebeinine (III), C27H45O3N, mp. 240-242 degrees C. On the basis of the IR, 1HNMR, 13CNMR and MS of zhebeinine (III), the structure of zhebeinine (III) has been established as 5 alpha, 14 alpha-cevanine-3 beta, 6 alpha, 20 beta-triol.
