Abstract
From the fruits of Celastrus orbiculatus Thunb. a new beta-dihydroagarofuran sesquiterpene ester named 1beta,2beta,13-triacetoxy-9alpha-cinnamoyloxy-beta-dihydroagarofuran (1) has been isolated along with two known compounds, 6alpha-acetoxy-1beta,9beta-dibenzoyloxy-8beta-hydroxy-beta-dihydroagarofuran (2), and 1beta, 6alpha-diacetoxy-9beta-benzoyloxy-8beta-hydroxy-beta-dihydroagarofuran (3). Their structures were elucidated on the basis of spectroscopic data.
