摘要
用原子力显微镜 ( AFM)对西洋参多糖的微观形貌进行观察 ,发现 PPQ- d呈多股紧密并行螺旋形排列 .
The microshape of polysaccharide isolated from panax quinquefolium L. known as PPQ d was observed by means of atomic force microscopy (AFM). From the images, the parallel spiral polystrands can be found and it is supposed that the phenomenon is resulted from the hydrogen bond association of the uronic acid containing polysaccharide chains among the molecules.
