| Summary: | Resveratrol is a natural bioactive polyphenolic compound found in many plants such as grapes, peanuts and Polygonum cuspidatum. It has a variety of biological activities including antioxidant, antibacterial and anti-inflammatory, anti-cardiovascular disease and anti-tumor activities, and has been widely applied in the fields of foods, medicine and daily chemical products. However, due to its unstable nature and poor water solubility, its application scope is limited. Therefore, the improvement of its bioavailability by using delivery systems will be a key research direction. In this paper, the physical and chemical properties and biological activities of resveratrol are summarized, and the resveratrol delivery systems developed in recent years are reviewed, and problems with some of these systems are pointed out. We hope that this review will provide a reference for the development of new resveratrol delivery systems.
