Abstract
A new chlorine-containing glucosyl-fused compound, crassifoside H (1), was isolated from the EtOH extract of the rhizomes of Curculigo glabrescens. The structure was established on the basis of MS, IR, 1D and 2D NMR experiments. In addition, seven known compounds (2 - 8) were isolated and identified by spectroscopic analysis and comparison of their spectral data with those reported previously. All the compounds were isolated from this plant for the first time. The free radical scavenging activity of the isolated compounds was evaluated by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. Compounds 1 and 2 showed strong radical scavenging activities. The primary structure-activity relationship is also discussed.
