Abstract:Objective:To isolate and identify maltol and maltol 3 O β D glucoside and argininyl fructosyl glucoside in red ginseng,and prove that they are products of processing through comparative analysis and artificial synthesis of different products of ginseng. Method:Column chromatography,spectral analysis,TLC scanning quantitfication,amino acid analysis and artificial synthesis on simulated conditions.Result:Maltol and its glycoside are peculiar components in red ginseng,and the content of argininyl fructosyl glucoside in red ginseng the product of processing is three times higher than that of white ginseng.Conclusion:Maillard reaction exists in the processing of red ginseng,thus proper control of this reaction helps improve the quality red ginseng.
