摘要： Arginyl-fructose (AF) and arginyl-fructosyl-glucose (AFG) are products of the Maillard reaction between arginine and reducing sugars during the thermal treatment of Asian ginseng (Panax ginseng C.A. Meyer). AF and AFG are widely distributed in red ginseng. Because there is no AFG in fresh Asian ginseng, the objective of the present study was to identify the arginine derivatives present in fresh Panax quinquefolius L. Two compounds obtained from P. quinquefolius L. were identified as AF and AFG by comparing the C-13 NMR and MS (mass spectrometry) spectra with those of standards. We propose that the Maillard reaction may exist in the fresh plant and not only during the thermal processing of ginseng. The antioxidant activities of AF and AFG were investigated in vitro. The data indicate that the Maillard reaction products AF and AFG contribute to the antioxidant activity of P. quinquefolius L. (C) 2012 Elsevier Ltd. All rights reserved.
