  Abstract Cellobiose, maltose, and 4- O -methyl- d -glucose were treated with 0.1–20m m 2-anthraquinonesulfonic acid in 0.1 m sodium hydroxide at 40°. The hydroxy carboxylic acids formed were separated by ion-exchange, and analyzed by g.l.c.-m.s. as their per(trimethylsilyl) derivatives. The acidic oxidation products of cellobiose were further fractionated into aldonic acids and carboxylaldoses by ion-exchange

  摘要在0.1 m氢氧化钠中于40°C用0.1–20m m 2-蒽醌磺酸处理纤维二糖，麦芽糖和4-O-甲基-d-葡萄糖。通过离子交换分离形成的羟基羧酸，并通过glc-ms分析其全（三甲基甲硅烷基）衍生物。通过离子交换色谱将纤维二糖的酸性氧化产物进一步分馏为醛糖酸和羧醛糖。用硼氢化钠还原分离的羧基醛糖，然后在水解之前和之后通过glc-ms进行分析。糖的O-d-葡萄糖基和O-甲基取代的产物除了2-C-羧基戊糖外，还由赤藓酸，阿拉伯酸，核糖酸，葡糖酸和甘露酸组成。还原性d-葡萄糖单元的未取代产物为甲酸，乙醇酸，2-脱氧电子，
