2D NMR对金钱松皮中的一个三萜皂苷进行结构解析

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.%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.
