Abstract

Abstract: Two new sesquiterpene compounds obtained from the leaves of Chinese bittersweet (Celastrus angulatus.M) were identified as 1β-cinnamoyloxy-9β-(2-hydroxy)-isobutyryloxy-2β,6α,8α,15-tetraacetoxy-4α-hydroxy-β-dihydroagarofuran(1) and 1β-benzoyloxy-9β-(2-hydroxy)-isobutyryloxy-2β,6α,8α,15-tetraacetoxy-4α-hydroxy-β-dihydroagarofuran(2) respectively by ¹H NMR, ¹³C NMR and 2D NMR techniques. The ¹H and ¹³C NMR and carbon-13 NMR data of the two compounds were completely assigned.

Key words: ¹H NMR, ¹³C NMR, Celastrus angulatus, Sesquiterpene, β-Dihydroagarofuran, Structure Elucidation
