摘　　要：红参加工过程中，鲜人参中的麦芽糖和精氨酸经加热后发生梅拉德反应而生成一种新的化合物，即精氨酸糖苷（ＡＦＧ）．反应必须在酸性（ｐＨ＜３．０）条件下进行，且水分的增加可抑制ＡＦＧ的生成量．Arginyl fructosyl glucose(AFG),a new nitrogenous compound,was produced by the Maillard reaction during the heat treatment for preparation of red ginseng from maltose and arginine from fresh ginseng.The content of AFG is 4 28% in red ginseng,0 20% in white ginseng.It wasn′t detected in fresh ginseng.Although arginine and maltose were found in the aconite root,angelicae radix and astragali radix,only the trace amount of AFG was produced by the heat treatment of these medicinal plants.The content of AFG and uronic acid increased along with increase in cultivating years.It was found that acidic conditions(pH<3 0) were necessary for proceeding Maillard reaction between arginine and maltose.The AFG decreased along with increase of water.
