【Abstract】 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.更多还原
