“…Hence the gradual increase in the flavonoid content at a higher rate in the UV treated seedlings than that of control seedlings can be explained by the higher accumulation of flavonoids as a defence mechanism in response to UV exposure. Our findings are in agreement with that of GonzalezAguilar et al [27] who reported an increase in flavonoid content in mango, on exposure to UV radiation. Nowadays, flavonoids have gained considerable interest as they are found to be very effective contributors involved in protection against cardiovascular disorder by mitigating the oxidation of LDL as well as prevention of several other degenerative diseases [28].…”

Objective: To evaluate the effect of ultraviolet (UV) radiation on the therapeutical and oxidative stress status of fenugreek seedlings during the post-germination phase. Methods:The seeds of Trigonella foenum-graecum L. were subjected to UV radiation of different wavelengths UV 254 nm, UV 365 nm and the combination of 254 nm and 365 nm UV during the course of germination up to 96 h. Free radicals scavenging activity, in vitro antidiabetic activity as well as total phenol (TPC) and flavonoid (TFC) contents were evaluated up to four days of germination stages. Analysis of total activities of superoxide dismutase (SOD), peroxidase, catalase and NADPH oxidase (NOX) was conducted using non-denaturing polyacrylamide gel electrophoresis along with histochemical detection of H2O2 and superoxide radical localisation, lipid peroxidation and plasma membrane integrity was also performed. Results:Overall it was observed that the sprouts exposed to UV 365 nm exhibited a significant enhancement in free radical scavenging as well as antidiabetic activity at the 48h stage of germination. Interestingly highest phenol and flavonol content were also stimulated at the same stage by UV 365 nm. The effect of UV irradiation was evident on the localisation of H2O2 and superoxide radical. The on gel assay revealed that the total activities of the antioxidant enzymes were extensively elevated by UV irradiation. Conclusion:The results suggest that the UV irradiation technology can be implemented for the enhancement of nutraceutical properties of sprouts also UV exposure helps in the induction of the antioxidant enzyme system which may be beneficial for oxidative stress management in plants during germination phases.

“…Similar beneficial effects of UV-C on quality were reported on other postharvest fruits like tomato (Barka et al 2000), strawberry (Mortazavi et al 2014), and mango (González-Aguilar et al 2007). However, additional studies will be needed on the impact of UV-C on the biochemical and molecular response of host fruit.…”

Significant losses in harvested melon can be directly attributable to decay fungi. In the present study, the use of UV-C treatment combined with biocontrol yeast, Pichia cecembensis, was evaluated for their ability to control postharvest decay of melon fruits after they were artificially inoculated with Fusarium oxysporum and Alternaria alternata. Natural infection of fruit was also assessed. As a stand-alone treatment, UV-C or P. cecembensis significantly reduced Fusarium rot and Alternaria rot, and also the level of natural infection on melon fruit, relative to the untreated control. The combination of UV-C or P. cecembensis, however, provided a superior level of decay control on artificially inoculated and naturally infected fruit, compared to either treatment alone. None of the treatments impaired fruit quality. Integrating the use of UV-C treatment with biocontrol yeast has potential as an effective method to control postharvest decay of melon.

“…These compounds are often regarded as an antioxidant, which acts as a protective mechanism against oxidative compounds. UV-C irradiation increased the total phenols and total flavonoids of Haden mango as compared to control (Gonzalez-Aguilar et al 2007). In blueberries, UV-C irradiation increased antioxidant activity, phenolics and total anthocyanin of fruit (Wang et al 2009).…”
