From the inner bark of Betulapendula, four new disaccharide glycosides, two of (−)-rhododendrol and two of platyphyllone, were isolated along with a new trisaccharide glycoside of (−)-centrolobol and several known compounds. The structures were elucidated by high field 1H and 13C NMR spectroscopy. Assignments of 1H and 13C NMR spectra were made by H,H- and C,H-COSY.
