Today, the use of a diet containing antioxidants and determination of antioxidant capacity of natural products would be beneficial to human health because oxidative stress is associated with several pathologies like cardiovascular, neurodegenerative, cancer and even aging. Curcumin, as an important biologically active polyphenolic compound, has wide range of beneficial biological and pharmacological activities e.g., antioxidant and anti-cancer, curcumin plays a significant beneficial and pleiotropic regulatory role in various pathological conditions including cancer, cardiovascular disease, Alzheimer's disease, inflammatory disorders, neurological disorders, and so on. Despite such phenomenal improvements in medicinal applications, the clinical implication of native curcumin is delayed due to it is practically water-insoluble and has low bioavailability. Therefore, many technologies have been developed and applied to overcome this limitation by utilizing an efficient delivery system.
