通过核磁共振谱并结合文献对一个三萜皂苷dammar-24(25)-ene-3β,6α,12β,20(S)-tetraol-20-O-β-D-pyranoglucoside进行结构解析.通过2D NMR(1H-1H COSY、HMQC、HMBC)对其进行了NMR全归属.
Structural analysis of a triterpene saponindammar-24(25)-ene-3β,6α,12β,20(S)-tetraol-20-O-β-D-pyranoglucoside by nuclear magnetic resonance spectroscopy combined with literature. 2D NMR (1H-1H COSY, HMQC, HMBC) were all assigned to NMR.
