Abstract
The chemical and hydroxyl radical (OH) scavenging activity changes of ginsenoside Rb1 (Rb1) by heat processing were investigated in this study. Rb1 was changed into 20(S)-Rg3, 20(R)-Rg3, Rk1, and Rg5 by heat processing through glucosyl elimination and epimerization of carbon-20 by SN1 reaction. The glucosyl moiety, separated from Rb1, made Maillard reaction product (MRPs) with glycine. The generations of 20(S)-Rg3 and MRPs were related to the increased OH scavenging activity of Rb1 by heat processing.
