A novel agarofuran sesquiterpene polyol ester, 1β, 2β, 6α, 15β-tetracetoxy-8β, 9α-dibenzoyloxy-β-dihydroagarofuran (celahin D) (1), two known analogues of 1, 1β-acetoxy-8β, 9α-dibenzoyloxy-4α, 6α-dihydroxy-2β(α-methylbutanoyloxy)-β-dihydroagarofuran (2) and 1β-acetoxy-8β, 9α-dibenzoyloxy-6α-hydroxy-2β(α-methylbutanoyloxy)-β-dihydroagarofuran (3), and a known cytotoxic sesquiterpene pyridine alkaloid, emarginatine E (4) were isolated from the stems of Celastrus hindsii BENTH. Three known triterpenes, loranthol (5), lupenone (6) and friendelinol (7) were also obtained from the titled plant. Structural elucidation of compound 1 was established by 2D NMR spectra.
