摘要: 从四川产家种贝母新种——瓦布贝母(Bulbus Fritillaria Wabuensis S.Y.Tang et S.C.Yueh)鳞茎中分离出一生物碱.经采用DEPT、1H-1HCOSY、13C-1HCOSY MMR等多种技术对化学结构及构型进行了研究,确证该生物碱为西贝素-β-氮氧化物(imperialine-β-N-Oxide).

关键词: 瓦布贝母, 西贝-β-氧化物, 2DNMR

Abstract: The alkaloids were isolated from the bulb of Fritillaria wabuensis S.Y.Tang et S.C. Yueh the best "Chuan Bei" cultivated in Sichuan Province, the structure and conformation of an alkaloid was studied and determined as imperialine-β-N-Oxide by 1H-1HCOSY、13C-1HCOSY MMR 2D-nuclear magnetic resonance technique, In this paper, we report the detailed research of very rare imperialine-β-N-Oxides in nature using NOESY,HMQC and HMBC 2D NMR new technique.

Key words: Fritillaria wabuense, Imperialine-β-N-Oxide, 2D NMR
