摘要:

从忍冬科药用植物金花忍冬(Lonicera chrysatha)中首次分离得到一 新的二聚体环烯醚萜甙——金花忍冬素(chrysathain). 采用1H-1H COSY、HMQC、HM
BC及NOESY二维谱技术鉴定了此化合物的化学结构及构型,并对其1H和13C NMR的谱峰进行了全归属.

关键词: NMR, 归属, HMQC, 金花忍冬, 环烯醚萜甙

Abstract:

A new dimeric iridoid glucoside, chrysathain, was isolated from the Chinese medicinal plant Lonicera chrysatha. Its structure and configuration were e
lucidated by 1D and 2D NMR spectroscopy. The 1H and 13C NMR chemical shifts of the compounds were assigned.

Key words: NMR, assignments, HMQC,  Lonicera chrysatha, iridoid glucoside, secologanin
