Study on Transformation of Ginsenosides in Different Methods

Figure 2

Data redrawn from [29]. Chemical transformation pathways of 20(S)-PPT ginsenosides Re, Rg2, and Rf. The transformation mechanisms of 20(S)-PPT ginsenosides Re, Rg2, and Rf include hydrolysis of saccharide substitution at C-6, Δ20(21) or Δ20(22) dehydration, and hydration addition reactions at C-24 and C-25.
