摘要
通过大孔树脂柱色谱,硅胶柱色谱及高效液相色谱法,从人参花蕾中分离得到15个化合物,并采用与标准品共薄层及与文献IR,13CNMR等数据比较,鉴定了其中的11个化合物,分别是β谷甾醇(1),20(R)原人参三醇(2),20(R)人参皂苷Rh1...
Fifteen compounds were isolated from flower buds of Panax ginseng C.A.Meyer by using alcoholic extraction,macroporous resin,silica gel and reversed phase column chromatography.Eleven of these compounds were identified as β sitosterol(1),20( R ) protopanaxatriol(2),20(R) ginsenoside Rh 1(3),20( R ) ginsenoside Rg 2(4),20( S ) ginsenoside Rg 2(5),ginsenoside Re(6),ginsenoside Rd(7),ginsenoside Rc(8),ginsenoside Rb 2(9),gypenoide ⅩⅦ(10) and notoginsenoside E(11),respectively,by means of spectral analyses and chemical evidences.Among them,20( R ) protopanaxatriol(2)was obtained for the first time from the flower buds,and gypenoide ⅩⅦ(10) and notoginsenoside E(11) were isolated from the title plant for the first time.
