摘要
20 (R)和 2 0 (S) 人参皂甙 Rg2 属于达玛烷型四环三萜类化合物 .应用 2DNMR技术 :1 H 1 HCOSY、HMQC和HMBC全归属 2 0 (R)和 2 0 (S) 人参皂甙 Rg2 碳和氢质子信号 ,为该类型化合物的结构鉴定提供波谱学依据 .
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). \;
