摘要/Abstract

摘要： 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.

Abstract: A triterpene saponin was extracted from the barks of Pseudorix kaempferi for the first time,and determined to be dammar-24(25)-ene-3β, 6α, 12β, 20 (S)-tetraol-20-O-β-D-pyranoglucoside on the basis of NMR analysis. The chemical shifts of this compound were completely assigned using 2D NMR spectroscopy.

Key words: NMR, chemical shift, triterpene saponin, pyranoglucoside, Pseudorix kaempferi Gord
