STRUCTURE OF PINGBEIMINE C

摘要: 本文报道自东北平贝母(Fritillaria ussuriensis Maxim)中分得一种新的C-去甲-D-异甾体生物碱,命名为平贝碱丙(pingbeimine C)。根据红外、质谱、氢谱、碳谱及X-射线衍射,确定其结构式为Ⅳ式。

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.
