An efficient procedure for preparing main acylated pentasaccharides from Polygalae Radix using integrated extraction–adsorption method followed by semi-preparative high performance liquid chromatography

In the present study, an efficient preparative procedure was developed for the preparation of three main acylated pentasaccharides from Polygalae Radix using integrated extraction–adsorption method followed by semi-preparative high performance liquid chromatography. Firstly, the acylated pentasaccharides were simultaneously extracted and purified by column chromatographic extraction integrated with macroporous resin purification. Comparing this...
