Abstract:

In order to enhance the loading of naringin (NA) in OSA modified porous starch (OSAPS) by optimization experiments and further enhance the in vivo bioavailability of NA with the form of complex, OSAPS-NA complexes were prepared by antisolvent precipitation method and metabolic kinetic studies were performed on the complexes prepared under optimal conditions. The oral bioavailability of the raw NA material and the OSAPS-NA complex was evaluated by fitting the compartmental model and the statistical moment model. The result showed that when acetone was applied as the solvent, solvent co-precipitation combined with ultrasonication significantly enhanced the loading rate of NA in OSAPS, and the highest loading rate of NA in OSAPS was achieved when the volume ratio of antisolvent (n-hexane) was 0.6, the sonication time was 200 W and the sonication time was 20 min. The oral relative bioavailability results indicated that the area under the drug-time curve of NA in the OSAPS-NA complex prepared under optimal conditions was 9.80 times that of the original NA material, and the time to peak was reduced from 60 min to 15 min. The study successfully optimized the OSAPS-NA complex, resulting in approximately (71.49±2.26)% loading of NA. And by being loaded by OSAPS, the relative oral bioavailability of NA was increased by 9.80 times.
