Abstract: Two dammarane-type triterpenoid saponins, 20(R)-ginsenoside Rg2 and 20(S)-ginsenoside Rg2, were isolated from stems-leaves of Panax ginseng C.A.Mey.. In this paper, all of the 1H and 13C NMR chemical shifts of the two compounds were assigned through 1D NMR and 2D NMR with Pulse Field Gradient (PFG) techniques (GCOSY,GHMQC and GHMBC).

Key words: Panax ginseng C.A.Mey., 20(R) ginsenoside Rg2, 20(S) ginsenoside Rg2, 2D NMR with Pulse Field Gradient (PFE), complete assignment of 1H and 13C NMR chemical shifts
