Abstract
From the roots and epigeal parts ofHaplophyllum dauricum (L.) G. Don., new acylated courmarin glycosides have been isolated: dauroside A, C23H28O13, mp 145–147°C (ethanol), [α] 22D − 72.7° (methanol), and dauroside B, C30H32O14, mp 145–150°C (methanol) [α] 22D 0° (pyridine). Their structures have been established on the basis of chemical transformations and IR, UV, mass,1H NMR and13C NMR spectra.
