Abstract

A new C-nor-D-homosteroid alkaloid, C₂₇H₄₃O₆N, mp 171.5～173℃, named pingbeimine C, was isolated from the bulb of Fritillaria ussuriensis Maxim. On the basis of IR, MS, ¹HNMR and ¹³CNMR spectroscopic data, particularly X-ray crystallographic analysis, structure Ⅳ has been assigned to this alkaloid.
