Abstract:
From the root of Siphonodon celastrineus Griff. (Family Celastraceae), a new oleanane triterpene, 3β-acetoxy-11α-benzoyl-13β-hydroxyolean-12-one, named siphonodone, was isolated together with two known compounds, β- sitosterol and pristimerin. The identification and structure elucidation of the isolated compounds were established by analysis of the spectroscopic data, as well as comparison with the data of other structurally related compounds.
