Abstract
|
|
|
|
Strawberries have various fruit phenolics which provide biological activities such as antioxidant, anti-inflammatory, and anti-proliferative potential against various cancer cells. Previous studies showed that such phenolics might be enriched by ultraviolet irradiation (UV) after harvesting fruits and vegetables. In the present study, we investigated the effect of post-harvest ultraviolet irradiation on the biological activities of strawberries. When 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity, induction of quinone reductase activity, inhibitory effect on the proliferation of various human cancer cells, and inhibitory effect on the expression of inducible nitric oxide synthase (iNOS) of UV-irradiated strawberries using Maehyang, Akihime, and Red pearl, were evaluated, the biological activities were, in general, enhanced by ultraviolet irradiation after harvest.
