O-β-D-glucopyranoside (4) were obtained from the roots of Sanguisorba officinalis. Combined with acid hydrolysis derivatization, the absolute configurations of these new compounds were elucidated by comprehensive analyses of spectroscopic data including nuclear magnetic resonance (NMR), electrospray ionization high resolution mass (HRESIMS) as well as circular dichroism (CD). Compounds 1-4 exhibited
