利用电喷雾质谱技术分析红参水层提取物, 发现有不同于鲜参的成分, 经进一步分析证明在红参加工过程中鲜参中的麦芽糖和氨基酸发生了梅拉德反应, 生成了新的氨基酸衍生物. 通过产物的模拟合成, 电喷雾串联质谱以及傅立叶变换离子回旋共振质谱分析, 对这几种成分进行了深入研究, 鉴定出它们是麦芽糖分别与精氨酸, 谷氨酸和天冬氨酸反应生成的双糖苷, 是红参在加工过程中产生的特有成分.

关键词: 红参, 梅拉德反应, 麦芽糖, 精氨酸, 谷氨酸, 天冬氨酸, 糖苷

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
