“…Extracts from P. vulgaris spicas that contain major amounts of caffeic acid showed that its antioxidative activities may be responsible for the antinociceptive and antidiabetogenic properties in diabetic mice models (Raafat et al 2016). In this experiment, the caffeic acid content in P. vulgaris spicas significantly increased under UV-B radiation, which is consistent with reports of Luis et al (2007) and Manaf et al (2016). Previous studies have reported that caffeic acid has strong photoprotective activity against UV-B radiation in both in vivo and in vitro experiments (Saija et al 2000).…”

“…In this study, the total phenolic contents in spicas of P. vulgaris under UV-B radiation were slightly higher than those of control treatment. Similar results were obtained by Manaf et al (2016) and Inostroza-Blancheteau et al (2014). Many studies have shown that phenolic compounds absorb in the UV-B electromagnetic region (280-320 nm) that and these compounds function as ROS scavengers to protect plants against UV-B radiation (Tegelberg et al 2001;Ortuñoa et al 2006).…”

Prunella vulgaris plants (full-bloom stage) were subjected to short-term (15 days) UV-B radiation in a growth chamber. UV-B radiation was effective at enhancing morphological and biomass characteristics and decreasing chlorophyll contents of P. vulgaris. Treatment of P. vulgaris with artificial UV-B radiation significantly increased peroxidase (POD), superoxide dismutase (SOD) and glutathione (GSH) activities compared to the control treatment. UV-B radiation significantly increased the levels of hydrogen peroxide (H 2 O 2 ), malondialdehyde (MDA) and proline in leaves of P. vulgaris compared to those of control plants. In addition, the contents of total flavonoids, rosmarinic acid, caffeic acid and hyperoside significantly increased under UV-B radiation. The total phenolic levels also increased under UV-B treatment. These results demonstrated that short-term UV-B radiation can enhance production of secondary metabolites in P. vulgaris, resulting in increased spica yield compared to that of control plants.

“…Effect of UV on vegetative and physiological parameters of callus differed according to its type and exposure time (Cetin, 2014). This results in line with Manaf et al (2016) who found that long exposure time to UV-B increased all growth parameters in Echinacea purpurea callus.…”

“…The concentration of phenolics differed according to UV-C irradiation distance, irradiation duration and incubation period as Cetin (2014) found in Vitis vinifera callus, so calli exposed to UV-C for 5 min with 30 cm distance apart after 24 h had the highest total phenolic content. Also, 2 h of exposure time to UV-B of Echinacea purpurea callus increased the total phenolics and the maximum increase in cell suspension was achieved by 4 h (Manaf et al, 2016).…”

Physiological impact of different exposure periods (1, 2 and 3 h) of UV-C (253.7 nm) on alkaloids and hyoscyamine production in 21-days aged callus of Egyptian henbane was investigated. Results showed that the concentration of total alkaloids was increased by 2.7 and 2.3 times after exposure to UV-C for 2 or 3 h, respectively more than unstressed callus. Also, data of HPTLC revealed that 2 h exposed-callus accumulated the highest amount of hyoscyamine which similar to the amount in wild leaves but it was more 3.1 times than control. Increment of alkaloids concentration was attributed with high accumulation of non-enzymatic antioxidants as free amino acids, free phenolics and glutathione and increased of peroxidase and superoxide dismutase activity as well as reduction of H 2 O 2 concentration. Also, 2 h exposed-callus to UV-C showed high expression of electrophoretic protein bands with molecular weights 109, 42 and 29 KDa. All exposure times to UV-C increased both fresh and dry weight of callus compared to unstressed one. Short exposure time of UV-C enhanced the amount of Chl. a and b in callus than other treatments. All exposure periods of UV-C decreased the concentration of carotenoids, anthocyanine, proline and total carbohydrates than control. Long exposure period of UV-C modified the callus cells shape by induction large spherical cells and lysigenous intercellular spaces. It can be concluded that 2 h exposure time of UV-C is effective treatment for enhancement both alkaloids and hyoscyamine content in callus of Egyptian henbane.
