Natural compounds as carriers for hydrophobic drugs have been increasingly used in drug delivery systems. In this study, disodium glycyrrhizin (NaGA), tannic acid (TA) and camptothecin (CPT) were firstly used to prepare the camptothecin solid dispersion (CPT SD). When dissolved in a solution medium, NaGA self-assembled to form micelles and CPT was encapsulated in micelles, meanwhile, TA connected with NaGA through hydrogen bonds to form a contract shell.
