Three new highly esterified β-dihydroagarofuran sesquiterpenes (1-3) were isolated from the root barks of Celastrus angulatus Max. together with eight (411) known ones. The new compounds were identified as 1β-picolinoyloxy-2β,6α-diacetoxy-8β,13-diisobutanoyloxy-9α-benzoyloxy-4α-hydroxy-β-dihydroagarofuran (1), 1β-picolinoyloxy-2β,6α-diacetoxy-8β,13-diisobutanoyloxy-9α-furanoyloxy-4α-hydroxy-β-dihydroagarofuran (2), and 1β,6α-diacetoxy-2β-nicotinoyloxy-8β,13-diisobutanoyloxy-9α-benzoyloxy-4α-hydroxy-β-dihydroagarofuran (3) on the basis of spectroscopic methods. Compounds 1-11 were all possessed cytotoxic activities against three human tumor cell lines by MTT assay.
