Using a medium pressure liquid chromatographic system, a new triterpene lactone named glyuranolide [3 beta, 22 alpha-dihydroxy-11-oxo-delta 12-oleanene-27 alpha-methoxy carbonyl-29-oic acid (29, 22 alpha-) lactone.] was isolated from the crude sapogenins of Glycyrrhiza uralensis Fisch. Its structure was elucidated by IR, UV, FAB-MS, and various NMR spectra (including NOE, BBD, INEPT, SR, COSY, NOESY etc.).
利用中压液相色谱系统，从甘草粗皂苷元中分离出一种新的三萜内酯，命名为甘草内酯[3β, 22α-二羟基-11-氧代-Δ12-齐墩果烯-27α-甲氧基羰基-29-酸(29, 22α-)内酯]。通过红外光谱、紫外光谱、快原子轰击质谱以及各种核磁共振谱(包括核Overhauser效应谱、宽带去偶谱、异核多量子相干谱、自旋回波谱、化学位移相关谱、核Overhauser效应相关谱等)对其结构进行了阐明。
