Two coumarin glycosides have been isolated from an aqueous ethanolic extract of the epigeal part of Haplophyllum obtusifolium: (I) - C16H16O10, mp 164-166 deg C, <α>D -52.4 deg (dimethylformamide); and (II) - C26H26O12, mp 206-208 deg C, <α>D -110.5 deg (pyridine).It has been established on the basis of chemical transformations and spectral characteristics that (I) has the structure of fraxetin 7-O-β-D-glucopyranoside and (II) that of scopoletin 7-O-(6'-O-feruloyl-β-D-glucopyranoside).
