  The aim of this study was to evaluate the contents of 2-O-?-D-glucopyranosyl-L-ascorbic acid in rhizomes, stems and leaves from Lycium barbarum. Rhizomes, stems and leaveswere extracted and the content of 2-O-?-D-glucopyranosyl-L-ascorbic acid and non glucosylated, free ascorbic acid was determined by HPLC-DAD. 2-O-?-D-glucopyranosyl-L-ascorbic acid was found in all goji plant tissues investigated.

  人们越来越意识到枸杞子的生物活性化合物（主要是抗坏血酸等抗氧化剂）对健康的益处。最近，报道了一种来自枸杞的抗坏血酸类似物，2-O-α-D-吡喃葡萄糖基-L-抗坏血酸。在大鼠中，该类似物以游离维生素 C 的形式被完整吸收，因此被提议作为维生素 C 原。该类似物的合成要求较高且费力，因此需要寻找可靠的天然来源。关于枸杞植物其他部分中类似物存在的知识尚缺乏。本研究的目的是评价枸杞根茎、茎和叶中2-O-β-D-吡喃葡萄糖基-L-抗坏血酸的含量。提取根茎、茎和叶，用HPLC-DAD测定2-O-β-D-吡喃葡萄糖基-L-抗坏血酸和非糖基化游离抗坏血酸的含量。在所有研究的枸杞植物组织中都发现了2-O-β-D-吡喃葡萄糖基-L-抗坏血酸。以干重计，叶中含有 3.34 毫克/100 克，茎中含有 4.05 毫克/100 克，根茎中高达 12.6 毫克/100 克。然而，枸杞中的类似物含量要高得多（40 至 280

  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-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.

  本发明提供了一种新型抗坏血酸衍生物作为一种前维生素C，与传统已知的2-O-(α-D-葡萄糖吡喃基)抗坏血酸相比，在体内具有更好的稳定性和更长的寿命。该新化合物2-β-(-D-葡萄糖吡喃基)抗坏血酸的组成物已从植物中提取，例如从宁夏枸杞和/或枸杞。含有2-O-(β-D-葡萄糖吡喃基)抗坏血酸的组成物可以使用β-D-葡萄糖基转移酶酶法合成。可以从这些组成物中制备纯的2-O-(β-D-葡萄糖吡喃基)抗坏血酸。另外，2-O-(β-D-葡萄糖吡喃基)抗坏血酸也可以通过化学合成制备。与相应的α-D-葡萄糖吡喃基衍生物相比，2-O-(β-D-葡萄糖吡喃基)抗坏血酸在体内摄入时具有更高的稳定性和更长的寿命，因此非常适合作为前维生素C用于化妆品和食品中。
