D-异抗坏血酸上游产品

D-异抗坏血酸下游产品

D-异抗坏血酸制备

1、以玉米淀粉为原料，通过发酵成葡萄糖酸来制得。日本藤泽药品公司采用的工艺过程是：由玉米淀粉制得葡萄糖，然后制成2-古罗酮糖酸甲酯(Methly2-ketogluconate)，用甲醇钠处理得到异抗坏血酸钠，再通过离子交换树脂脱盐，即制得异抗坏血酸。

2、两步法先生物合成2-酮基-D-葡萄糖酸，然后化学合成D-异抗坏血酸。能氧化葡萄糖生成2-酮基-葡萄菌、粘质赛氏杆菌、欧文氏菌等。发酵完成后，用碳酸钙中和发酵液，然后进行分类分离和提取。2-酮基2-D葡萄糖酸可由发酵液经游离酸提取或钙盐提取而得。

（1）游离酸提取

（2）钙盐提取

（3）合成D-异抗坏血酸

3.　采用发酵法。由荧光极毛杆菌（Pseudomonas fluorescence）使葡萄糖通气发酵（28℃，50h），得α- 酮葡糖酸钙，接着用甲醇和硫酸使其形成甲酯。添加甲醇氢氧化钠溶液进行烯醇化反应而得。
