摘要
运用 ２Ｄ ＮＭＲ技术，如 ＤＱＦ １Ｈ－１Ｈ ＣＯＳＹ，ＨＭＱＣ，ＨＭＢＣ，ＴＯＣＳＹ等，对 ３个原人参 二醇型双糖链配糖体人参皂甙－Ｒｄ，三七皂甙－Ｅ和六叶胆皂甙ＸＶＩＩ的氢和碳的化学位移首次 进行了全归属．
Three protopanaxadiol bisdesmosides were elucidated as ginsenoside-Rd, gypeno- side XVII, and notoginsenoside-E on the basis of MS and NMR data comparison with those in the references. The complete assignments of 1H and 13C NMR chemical shifts of these 3 compounds were obtained by means of 2D NMR spectra, such as DQF 1h-1H COSY, HMQC, HMBC and TOCSY.
