Natural Nanoparticles in Gegen-Qinlian Decoction Promote the Colonic Absorption of Active Constituents in Mice with Dextran Sulfate Sodium-Induced Ulcerative Colitis.

ABSTRACT: Background/Objectives: The aim of this study was to reveal the influence of the natural nanoparticles (Nnps) isolated from Gegen-Qinlian Decoction (GQD), i.e., GQD-Nnps, on the intestinal absorption and pharmacokinetic properties of several representative active GQD constituents. Methods: The morphology of GQD-Nnps was examined using scanning electron microscopy (SEM). Protein and polysaccharide contents were measured using the bicinchoninic acid (BCA) assay and phenol-sulfuric acid method, respectively. Major GQD constituents were quantified by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Formation mechanisms were explored using dynamic light scattering (DLS), Fourier transform infrared spectroscopy (FTIR), and high-resolution mass spectrometry (HRMS). Pharmaco
