Ultisil PG-C18 column is a new generation of dedicated column which has unique selectivity for the analysis of ginsenoside with good peak symmetry and high column efficiency. As active ingredients in panax notoginseng, ginseng, red ginseng and American ginseng, Ginsenosides Rg1 and Re also have similar chromatographic properties. It is usually difficult to achieve a resolution of 1.5 on conventional C18 columns (i.e., baseline separation) for that they are very sensitive to the proportion of acetonitrile in the mobile phase. Even a 1% nuance in that will cause a great change in their appearing time, so they can only be seen and separated on the C18 column at about 20% of acetonitrile. Due to this special property, the choice of adjusting the mobile phase to increase the resolution is restricted.
