Abstract

Three new sesquiterpene polyol ester compounds angulatins S-U, together with three known compounds were isolated from Celastrus angulatus Maxim. According to mainly 1D NMR and 2D NMR analysis, the structures of the new compounds were completely determined as angulatin S (1β-furoyloxy-2β,8α-diisobutanoyloxy-9β-benzoyloxy-15-acetoxy-4α,6α-dihydroxy-β-dihydroagarofuran), angulatin T (1β,2β,6α-triacetoxy-8β,15-diisobutanoyloxy-9α-benzoyloxy-β-dihydroagrofuran), and angulatin U (1β,6α,15-triacetoxy-8β-isobutanoyloxy-9α-benzoyloxy-β-dihydroagarofuran).
