摘要: 从刺南蛇藤中首次分离到一对差向异构体,用NMK方法(1H NMR,13C NMR,DEPT,1H-1H COSY,13C-1H COSY,NOESY,HMBC)并结合其它结构信息,确定其化学结构为;1α,6β,8α,13-四乙酰氧基-9α-苯甲酰氧基-β-二氢沉香呋喃(1)和1α,6β,8α,13-四乙酰氧基-9β-苯甲酰基-β-二氢沉香呋喃(2).其中1为新化合物,命名为Celastrine。

Abstract: A pair of epimers were isolated from Celastrus flagellaris Rupr,for the first time,their chemical structures were elucidatcd as 1α,6β,8α,13-tetraacetoxy-9α-benzoyloxy-β-dihydroagarofuran(1) and lα,6β,8α,13-tetraacetoxy-9β-benzoyloxy-β-dihydroagarofuran(2) mainly by 1H-1H COSY,13C-1H COSY,NOESY and HMBC spectra.Compound 1 is a new compound named as Celastrine.

Key words: Celastrus flagellaris, Celastrine, 2D NMR
