Electrospray ionization-mass spectrometric (ESI-MS) method was applied to detect the water-soluble extract of red ginseng. Several new amino acid derivatives were found to be produced by the Maillard reaction of maltose with different amino acids during the steaming and drying process involved in preparation of red ginseng. Four ninhydrin-positive compounds were identified by ESI-MS-MS/FT-MS and isolated through the gel column chromatography. The results showed that they were the initial Maillard reaction products of maltose with arginine/glutamic acid/aspartic acid, which were special components of red ginseng.

Key words: red ginseng, Maillard reaction, maltose, arginine, glutamic acid, aspartic acid, glycoside
