Studies on Less Polar Ginsenosides of Different Process Methods by Electrospray Ionization Mass Spectrometry

Five different processed methods for ginseng were used to transferred ginsenosides with large molecule mass into low polar ginsenosides. The contents of low polar ginsenosides in these ginseng products were determined by ESI-MS. The results show that the high pressure steaming method make for increasing the concent of low polar ginsenosides, while soakage in vinegar is not good comparing with it.
