Synthesis And Characterization Of American Ginseng Polysaccharides Nanoparticles, Vincent Lee
Electronic Thesis and Dissertation Repository
This project was concerned with the synthesis of nanoparticles (NPs) by microfluidics from bulk ginseng polysaccharides (PS) isolated from American ginseng to design a new delivery system to improve the bioavailability of PS. Physicochemical analyses showed products of nanosizing as unimodal spheres with a diameter of ~19 nm. Pharmacological characterization studies in vitro of these nanoparticles of PS (NPPS) have demonstrated heightened immunostimulatory activity, and enhanced penetration across skin cell monolayer, which could be considered as evidence of increased bioavailability. Studies using PS sub-fractions with different molecular weights for NPPS synthesis showed that molecular weights is one of the parameters …
