Abstract
The chemical and hydroxyl radical (*OH) scavenging activity changes of ginsenoside Rb(1) (Rb(1)) by heat processing were investigated in this study. Rb(1) was changed into 20(S)-Rg(3), 20(R)-Rg(3), Rk(1), and Rg(5) by heat processing through glucosyl elimination and epimerization of carbon-20 by SN1 reaction. The glucosyl moiety, separated from Rb(1), made Maillard reaction product (MRPs) with glycine. The generations of 20(S)-Rg(3) and MRPs were related to the increased OH scavenging activity of Rb(1) by heat processing.Entities:
