Abstract
Ultraviolet radiation is a part of sunlight spectrum and is divided into three bands A, B, and C, due to the wavelength. Plants which are incapable of movements, protect themselves against this kind of radiation, by two enzymatic and non-enzymatic mechanisms. These mechanisms can be used in order to increase medicinal products. In This study, the effects of different UV-B dosages (application of different post harvest illumination durations 1, 2 and 4 hours) on the content of some antioxidant compounds (i.e., flavonoids, anthocyanin, total phenolic and lecopene contents), activity of PAL and total protein of ripe red tomato fruit (Lycopersicon esculentum Mill.) were studied. The amount of flavonoids increased in comparison with the control, in all treatments. The changes of anthocyanin content was similar to that of the flavonoids. UV treatment of 2 and 4 hours increased total phenolic compounds. Similar results were observed in lycopene content under UV-B. This radiation increased PAL activity, but decreased protein content. Thus, it is concluded that exposure of tomato fruit to UV-B increased antioxidant compounds.
