    Abstract:
    Luteolin has extensive biological effects, but its low water-solubility and oral bioavailability have restricted its application. In this study, we successfully prepared new zein-gum arabic (GA)-tea polyphenols (TP) ternary complex nanoparticles (ZGTL) as a delivery system to encapsulate luteolin using an anti-solvent precipitation method. Consequently, ZGTL nanoparticles showed negatively charged smooth spherical structures with smaller particle size and higher encapsulation ability. X-ray diffraction revealed the amorphous state of luteolin in the nanoparticles. Hydrophobic, electrostatic, and hydrogen bonding interactions contributed to the formation and stability of ZGTL nanoparticles, as indicated by fluorescence and Fourier transform infrared spectra analyses. The inclusion of TP improved the physicochemical stability and luteolin retention rate of ZGTL nanoparticles by forming more compact nanostructures under different environmental conditions, including pH, salt ion concentration, temperature, and storage. Additionally, ZGTL nanoparticles exhibited stronger antioxidant activity and better sustainable release capacity under simulated gastrointestinal conditions due to TP incorporation. These findings demonstrate that ZGT complex nanoparticles have potential applications as an effective delivery system for encapsulating bioactive substances in food and medicine fields.
