Abstract:

Three protopanaxadiol bisdesmosides were elucidated as ginsenoside-Rd,gypenosi de XVII, and notoginsenoside-E on the basis of MS and NMR data comparison with  thos e in the references. The complete assignments of 1H and 13C NMR  chemical  shifts of these 3 compounds were obtained by means of 2D NMR spe ctra,such as DQF 1H-1H COSY, HMQC, HMBC and TOCSY.

Key words: ginsenoside Rd, notoginsenoside E, gypenoside XVII, N MR complete assignments
