Abstract: The purpose of this experiment was to construct a mesoporous silicon-encapsulated resveratrol nano-delivery system. The nanosystem before and after loading resveratrol was characterized and analyzed by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, N2 adsorption-desorption, differential thermal-thermogravimetric analysis. Its light and heat stability properties and release laws in different pH buffers in vitro were explored. The results show that the mesoporous silica-encapsulated resveratrol nano-delivery system has a cross-linked network structure. The pore size, specific surface area and pore volume are 10.16 nm, 245.73 m2/g and 0.79 cm3/g, respectively, and the loading capacity could reach 39.44%. The framework structure is not destroyed after loading, and the optical and thermal stability of resveratrol is effectively improved. Meanwhile, the release rate of resveratrol after nanosystem loading is more than 80% within 2 h in two different pH buffers. The mesoporous silica-encapsulated resveratrol nanosystem has better performance and provides reference significance for the further development and utilization of resveratrol.

Key words: resveratrol, mesoporous silica, nano-delivery system, drug loading capacity, release rate, stability
