    • The present invention provides a novel ascorbic acid derivative as a provitamin C with improved stability in the body and prolonged life in the body compared to conventionally known 2-O-(α-D-glucopyranosyl)ascorbic acid.The composition comprising the novel compound 2-O-(β-D-glucopyranosyl)ascorbic acid has been extracted from plants such as from Ningxia Lycium barbarum L. and/or Lycium chinense Mill. The compositions comprising 2-O-(β-D-glucopyranosyl)ascorbic acid may be enzymatically synthesized using β-D-glucosyltransferase. Pure 2-O-(β-D-glucopyranosyl)ascorbic acid may be produced from such compositions. Alternatively, 2-O-(β-D-glucopyranosyl)ascorbic acid may be produced by chemical synthesis. The 2-O-(β-D-glucopyranosyl)ascorbic acid results in higher stability and a prolonged life of vitamin C when ingested in the body compared to the corresponding α-D-glucopyranosyl derivative, and is therefore highly suitable as a provitamin C to be used in cosmetics and foods.
    • 与常规已知的2-O-(α-D-吡喃葡萄糖基)抗坏血酸相比,本发明提供了一种新型抗坏血酸衍生物作为维生素C,具有改善体内的稳定性和延长的身体寿命。 从宁夏枸杞子和/或枸杞子植物提取含有新化合物2-O-(&bgr-D-吡喃葡萄糖基)抗坏血酸的组合物。 可以使用β-葡萄糖基转移酶酶法合成包含2-O-(β-谷氨酰-D-吡喃葡萄糖基)抗坏血酸的组合物。 可以从这样的组合物制备纯2-O-(&bgr-D-吡喃葡萄糖基)抗坏血酸。 或者,可通过化学合成制备2-O-(&bgr-D-吡喃葡萄糖基)抗坏血酸。 与对应的α-D-吡喃葡萄糖基衍生物相比,2-O-(&bgr-D-吡喃葡萄糖基)抗坏血酸在身体摄取时导致更高的稳定性和更长的维生素C的使用寿命,因此非常适合作为维生素 C用于化妆品和食品。
