【Abstract】 Studies showed that ginsenoside-Rh₂ has in-hibitory effect on many kinds of cancer cells andginsenoside-Rh₁ activates adenylate cyclase,with-out induction differentiation of cancer cells.Sinceginsenoside-Rh₁ and Rh₂ in ginseng is trace ele-mant,we produced two compounds through alka-line hydrolysis of the crude saponin of the leavesof American ginseng（Panax quinquefolium L.）.These compounds were proved to be ginsenoside-Rh₁（0.98%,yield）and -Rh₂（1.86%,yield）,respectively,by mearing mp,the mp of themixure with authentic sample,and comparing TLCand ¹³C-NMR with that of authentic sample.更多还原
