Abstract :Two sesquiterpene polyesters have been isolated from the ripe fruits of Euonymus japonicus Thunb. (Celastraceae) and shown to be two known compounds, 1β, 2β, 6α, 8β, 15-pentaacetoxy-9a - benzoyloxy-β-dihydroagarofuran (Ejap-4) and its 2-deacetoxy derivative (Ejap-3). Some physical data which have not reported in the previous paper are described and the anomalous upfield shift of the ^1H NMR signal associated with an acetoxy group at C-1 in each of the compounds is discussed.
