Abstract
|
|
|
|
The objective of this study is to provide basic information for developing a high-value ginseng product using ginseng saponin and prosapogenin. In order to achieve the proposed objective ginsenoside compositions of Black (BG) and Red (RG) ginseng extract with 95% ethyl alcohol were examined by means of HPLC. The crude saponin and ginsenoside composition of processed ginseng products were analyzed and compared, with BG topping the list with a crude saponin content of 7.53%, followed by RG (5.29%). Ginseng prosapogenin (ginsenosides Rg₂, Rg₃, Rg5, Rg6, Rh₁, Rh₄, Rk₁, Rk₃, F₁ and F₄) in BG was found to be contained almost 2.6 times as much as that in RG. Ginsenosides Rg₃, Rg6, Rk₁, Rh₄ and F₄ in BG in particular were found to be almost 3 times as much as those in RG. Rg6 and Rk₃ in BG were also found to be almost 4 times as much as those in RG.
