The effect of aspartic acid as a catalyst on the transformation of protopanaxadiol-type ginsenosides(PDG) and Maillard reaction in high temperature steam was investigated. The antioxidant activity of the reaction products in vitro was also determined. The results showed that PDG was transformed into 20 S-Rg3, 20 R-Rg3, Rk1 and Rg5; the transformation pathway was as follows: PDG → 20 S-Rg3/20 R-Rg3 → Rk1/Rg5. The contents of 20 R-Rg3 and Rg5 showed a gradual increase with increasing heating temperature, whil...
