Abstract: Chitosan derivative with glycyrrhetinic acid(GA), which was accumulated specifically in liver, was synthesized. By ion-crosslinking of TPP in GA-CTS solution, GA-CTS-TPP complex nanoparticles were obtained. The physicochemical properties of these nanoparticles were investigated by using TEM and DLS. The experiment in vitro BSA entrapped was studied. GA-CTS-TPP nanoparticles are well dispersed and stable in aqueous solution in 14 months.

Key words: Glycyrrhetinic acid, Chitosan, Liver targeting
