摘要: 从南蛇藤属植物苦皮藤中分离出两个新的β-二氢沉香呋喃型化合物:1β,2β,15-三乙酰氧基-8α-(α-甲基)-丁酰氧基-9β-苯甲酰氧基-4α,6α-二羟基-β-二氢沉香呋喃(化合物I)和1β,15-二乙酰氧基-8α-(α-甲基)-丙酰氧基-2β,9β-二苯甲酰氧基-4α,6α-二羟基-β-二氢沉香呋喃(化合物II).通过核磁共振(NMR,包括1H NMR、13C NMR、DEPT、1H-1H COSY、NOESY、HSQC、HMBC)技术对化合物所有的1H和13C NMR信号进行了全归属和详细解析.

Abstract: Two new β-dihydroagrofuran compounds, 1β,2β,15-triacetoxy-8α-(α-methyl)-butanoyloy-9β-benzoxy-4α,6α- dihydroxy-β-dihydroagrofuran (compound I) and 1β,15-diacetoxy-8α-(α-methyl)-propionyloxy-2β,9β-dibenzoxy-4α,6α- dihydroxy-β-dihydroagrofuran (compound II), were isolated from Celastrus angulatus Maxim. The chemical shifts of the two new compounds were assigned by one- and two-dimensional nuclear magnetic resonance (NMR) techniques. Their structures were elucidated.

Key words: nuclear magnetic resonance (NMR), Celastrus L., β-dihydroagrofuran, Celastrus angulatus Maxim
