| Abstract: | Two dammarane type triterpenoid saponins, 20(%R%) ginsenoside Rg-2 and 20(%S%) ginsenoside Rg-2, were isolated from stems leaves of Panax ginseng C.A.Mey.. In this paper, all of the {} 1H and {} {13}C 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). ; |
