摘要
应用 2DNMR技术 :1 H 1 HCOSY、HMQC、HMBC全归属新化合物卷丹皂苷A和已知化合物麦冬皂苷D′的碳和氢质子信号 ,总结薯蓣皂苷元类型甾体皂苷的NMR特征 ,为该类型化合物的结构鉴定提供光谱学依据 .
A series of 2D NMR techniques, including COSY, HMQC and HMBC, were applied to the assignments of all their carbon and proton signals of lililancifoloside A (diosgenin 3 O {O α L rhamnopyranosyl (1→2) O [α L arabinopyranosyl(1→3)] β D glucopyranoside}) and ophiopogonin D′. The NMR characteristics of steroidal saponins for diosgenin type were summaried. Lililancifoloside A is a new compounds isolated from the bulbs of Lilium lancifolium Thunb. by authors. Ophiopogonin D′ is a known compound isolated from the title plant and its carbon and proton signals were assigned for the first time.
