标题:甜叶菊叶中含甜菊糖苷的鼠李糖或木糖的鉴定,化学合成及甜度评价
摘要:从甜叶菊叶中获得的甜菊糖苷越来越多地作为天然低热量甜味剂用于食品工业.其中,由葡萄糖残基组成的主要苷类(如甜菊苷和莱鲍迪苷a)的甜味已被广泛研究.然而,含有鼠李糖或木糖残基的次要天然产物的性质研究很少.在这项研究中,从我们正在发育的甜菊叶中提取了五种未报道的含有鼠李糖或木糖的甜菊糖苷,并评估了它们的甜度.鉴定了高度糖基化的甜菊糖苷,并使用质谱法通过碎片分析检查了它们的结构.这些糖苷的化学合成证实了它们的结构,并允许对少量甜菊醇糖苷进行感官评价.我们的研究表明,一种含木糖的糖苷莱鲍迪甙 Fx1 具有均衡的甜味,因此,它是食品工业中使用的天然甜味剂的有前途的候选者.

标 题:Kaurenoic acid glycoside precursors and methods of synthesis

摘要:Ent-kaurenoic acid glycoside precursor compositions and synthesis methods are provided. The KA-19-monoside, KA-19-bioside and KA-19-trioside precursors can be used as starting materials for a variety of kaurenoic acid based reactions. The precursors provide alternative synthesis pathways for steviol glycosides to the natural pathway based on Steviol biosynthesis. The alternative synthesis pathways using the precursors also circumvent the rate limiting step of the natural Steviol biosynthesis pathway. The precursors can be used individually or in combination to produce a mixture or individual steviol glycosides such as Rebaudioside A, Rebaudioside D or Rebaudioside M. Control over the precursor quantities and composition allows control over the composition of the resulting steviol glycosides that are finally produced.
