| Abstract: | Objective To improve the methods of isolation and identification of platycodins, to pro- vide scientific basis for the quality standardization of Platycodon grandiflorum(Jacq) A.DC. Methods Macroporous, us resin and thin layer silica gel are used as the medium of column chromatography, and the new expermental methods which apply first ESI-MS to analysis and identify for platycodins are established. Results Their structures are identified on the basis of spectral data and chemical properties as: platycodin-V and deapioplatycodin-D. Conclusions The stuctural elucidation of saponins allied compounds are simplified by using electrospray-MS technology. |
