Ultrasound processed nanoemulsion: A comparative approach between resveratrol and resveratrol cyclodextrin inclusion complex to study its binding interactions, antioxidant activity and UV light stability.


PMID 28427660

Abstract

Resveratrol is a naturally occurring therapeutic molecule used for treatment of diseases caused by oxidative stress. This investigation elucidates the advantages of fabrication of size controlled resveratrol inclusion complex. This has been done by encapsulating resveratrol-cyclodextrin inclusion complex in a phospholipid stabilized nanoemulsion formulated by ultrasonication emulsification method. The prepared nanoemulsion has been compared with resveratrol encapsulated nanoemulsion system. The morphology of the resveratrol nanoemulsion and inclusion complex nanoemulsion have been observed using transmission electron microscopy with average size 20.41±3.41 and 24.48±5.70nm respectively. The nanoemulsion showed good loading and release efficiency. The radical diminishing potential of resveratrol and its inclusion complex has been compared in nanoemulsion. The effect of UV irradiation (365nm) on resveratrol in different solvent systems (ethanol, water and nanoemulsion) indicated that nanoemulsion prevents degradation of resveratrol. Efforts have also been made to explore the interactions between bovine serum albumin and resveratrol in nanoemulsion.
