Glycyrrhizic acid encapsulated in zein/Astragalus polysaccharides nanoparticle: enhanced stability, bioactivity and sustained release.

Glycyrrhizic acid (GA) exhibits potent antiviral, anti-inflammatory, and hepatoprotective activities. However, its bioactivity is constrained by low stability under varying conditions, including pH and temperature. To improve its stability, GA was lo…
