  Synthesis of α-tocopheryl oligosaccharides

  摘要：

  As effective natural antioxidants, tocopherols and also their esters are frequently added to foodstuffs, pharmaceuticals and cosmetics. For increase of polarity, hence solubility in water, a series of alpha-tocopheryl oligosaccharides was synthesised using BF3-etherate. The pure alpha-tocopheryl beta-maltotetraoside as well as the higher homologues proved to be water-soluble. (C) 1997 Elsevier Science Ltd.
