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
