    摘要： Provided with a novel ascorbic acid derivative represented by the formula (I) and a method for preparing the same: wherein R1 and R2 are different from each other and, independently H or —CH2CH2—(O—CH2—CH2)n—OR3, wherein n is an integer from 2 to 400; and R3 is a lower alkyl group having 1 to 10 carbon atoms. The novel ascorbic acid derivatives of this invention have excellent characteristics such as long-lasting anti-oxidation effect, high solubility in both water and organic solvents, and high stability in an aqueous solution. Furthermore, the novel ascorbic acid derivatives are useful for feed, food, cosmetic and pharmaceutical products due to their low toxicity and high thermal stability.

    摘要翻译： 提供由式（I）表示的新型抗坏血酸衍生物及其制备方法：其中R1和R2彼此不同，独立地为H或-CH2CH2-（O-CH2-CH2）n-OR3， 其中n是2至400的整数; 并且R 3是具有1至10个碳原子的低级烷基。 本发明的新型抗坏血酸衍生物具有优异的特性，如持久的抗氧化效果，在水和有机溶剂中的高溶解度，以及在水溶液中的高稳定性。 此外，新型抗坏血酸衍生物由于其低毒性和高热稳定性而可用于饲料，食品，化妆品和药物产品。
