摘要：

A new sesquiterpene polyol ester, 1-beta-acetoxy-2-beta, 8-beta, 9-alpha-tribenzoyloxy-6-alpha-hydroxy-beta-dihydroagarofuran, was isolated from the root bark of Celastrus rosthornianus. Its structure was elucidated mainly on the basis of 1D and 2D NMR spectrometry. The complete assignment of the C-13 NMR chemical shifts, and the determination of H-1-H-1 weak couplings observed in the H-1 NMR spectrum were also carried out on the basis of the 2D NMR spectra.
