Three new sesquiterpene polyol esters from Celastrus angulatus. Issue 4 (3rd April 2022) - Zhao, Wei
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).
