  including alpha-D-man-(1 --> 2)-D man and alpha-D-man-(1 --> 2)-alpha-D-man-(1 --> 2)-D-man were formed when a highly concentrated mannose solution was incubated in the presence of alpha-mannosidase from Aspergillus niger. alpha-D-Man-(1 --> 2)-D-man and alpha-D- man-(1 --> 2)-alpha-D-man-(1 --> 2)-D-man were isolated by activated carbon chromatography followed by high performance liquid chromatography

  各种甘露寡糖，包括alpha-D-man-（1-> 2）-D man和alpha-D-man-（1-> 2）-alpha-D-man-（1-> 2）-当在来自黑曲霉的α-甘露糖苷酶存在下孵育高度浓缩的甘露糖溶液时，形成D-man。alpha-D-Man-（1-> 2）-D-man和alpha-D-Man-（1-> 2）-alpha-D-man-（1-> 2）-D-man是通过活性炭色谱分离，然后使用氨基硅胶柱进行高效液相色谱分离。除上述寡糖外，α-D-人-（1-> 3）-D-人，α-D-人-（1-> 6）-D-人和α-D-人- （1-> 2）-alpha-D-man-（1-> 6）-D-man也被分离出来。

• Sonication-Assisted Oligomannoside Synthesis
  作者：Christabel T. Tanifum、Cheng-Wei T. Chang

  DOI：10.1021/jo8019835

  日期：2009.1.16

  We have investigated the use of sonication for the synthesis of oligomannosides. A convenient sonication-mediated glycosylation protocol that is applicable to traditional glycosylation methods has been developed. This protocol can be applicable for activating glycosyl donors that are known to have low reactivity which enable the synthesis of oligomannosides of particular biological interest with the same efficiency.
