From the inner bark of Betula pendula, 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.
从 Betula pendula 的内部树皮中,分离出四种新的二糖苷,两种 (-)-杜鹃花醇和两种白杨酮,以及一种新的 (-)-centrolobol 三糖苷和几种已知化合物。通过高场 1H 和 13C NMR 光谱阐明了结构。1H 和 13C NMR 谱的归属由 H,H-和 C,H-COSY 进行。
