Abstract:
Objective To investigate the inclusion of ginsenoside Rg_3 with hydroxylpropyl-?-cyclodextrin (HP-?-CD) in aqueous solutions, inclusion molar ratio of host and guest molecules, and change of thermodynamic parameters during the inclusion process. Methods The measurements of the inclusion mechanism, inclusion molar of the host and guest molecules, and change of thermodynamic parameters were carried out by the following methods: phase solubility, IR, NMR, and TLC methods, respectively. Results The results indicated that the inclusion compound of ginsenoside Rg_3-HP-?-CD was formed. The content analysis of the inclusion compound showed that the inclusion ratio of ginsenoside Rg_3-HP-?-CD was 1∶1. The change in the thermodynamic parameters suggested that the inclusion could proceed (△G
