“…In the present research, the highest TPC and antioxidant activity observed in 6 dS/m and summer season. Similar results were also found in Mentha pulegium , Carthamus tinctorius , and Lactuca sativa . It suggests that the severe environmental conditions, mainly salinity, might induce phenolic biosynthesis, and consequently antioxidant activities.…”

“…Antioxidant activity might be attributed to the chemical structure of polyphenols, as well as synergistic or antagonistic effect of components present in the extract . Previous researches showed that flavonoids and related polyphenols contribute to antioxidant activity of many plant species such as medicinal plants, fruits, and vegetables . Previous studies revealed that the harvesting time has a significant influence on the flavonoid content in M .…”

The effect of different NaCl concentrations (control, 2, 4 and 6 dS/m) and three harvesting times in different seasons including spring (9 April), summer (5 July), and fall (23 September) was evaluated on essential oil (EO) yield, composition, phenolic, flavonoid content, and antioxidant activity of myrtle. Essential oil yield ranged from 0.2% in control and fall to 1.6% in moderate salinity (4 dS/m) and spring season. The main constituents obtained from gas chromatography/mass spectrometry analysis were α-pinene, 1,8-cineole, limonene, linalool, α-terpineol, and linalyl acetate in which α-pinene ranged from 11.70% in moderate and fall to 30.99% in low salinity (2 dS/m) and spring, while 1,8-cineole varied from 7.42% in high salinity (6 dS/m) and summer to 15.45% in low salinity and spring, respectively. Salt stress also resulted in an increase in total phenolic, flavonoid content, and antioxidant activity. The highest antioxidant activity based on DPPH radical scavenging activity, reducing power (FTC) and β-carotene/linoleic acid model systems was found in plants harvested in spring and summer in high stress condition. The lowest IC values obtained in 6 dS/m in spring (375.23 μg/ml) followed by summer (249.41 μg/ml) and fall (618.38 μg/ml). Eight major phenolic and flavonoid compounds were determined in three harvesting times using high performance liquid chromatography analysis. In overall, late harvesting time of myrtle in fall can lead to reduce the most of major EO components, while it can improve the amount of phenolic acids.

“…Similarly, it was also noted that the treatment of UV-C reduced the severity of decay during storage of strawberry fruit (Fragaria xananassava) by promoting the antioxidant capacity and enzyme activities, and contents of phenolics and anthocyanins [30]. The exposure of UV-C resulted in an increase of total phenolics and flavonoids, and antioxidant capacity in leaves of lettuce (Lactuca sativa L.) [31]. In general, the use of UV-C is beneficial in treatments against bacteria, fungi, and diseases, occurring during storage of crops and foods.…”

Alpinia zerumbet (Pers.) B.L. Burtt. & R.M. Sm is an important perennial ginger plant in the tropics with various uses as foods, dietary supplement, cosmetics, essential oil production and traditional medicines. In this study, essential oils, phenolic acids, fatty acids, kavains, total phenols and antioxidant activity in A. zerumbet plants exposed to UV-C were investigated. Number and weights of essential oils increased rapidly from 1 to 3 days of exposure. Major extend of essential oils was recorded in methyl cinnamate and followed by benzyl acetone. The correspondence to the accumulation of palmitic acid was 15 folds, in contrast to the strong reduction of stearic quantity was 10 folds at 3 days of treatment. Changes in chemical components and antioxidant capacity in A. zerumbet are differed reversely between the exposure of UV-C and heavy toxic chemicals. The exposure of UV-C is beneficial for the increasing of essential oil production in A. zerumbet.

“…Los antioxidantes tienen una función de protección similar en plantas y animales, inclu yendo los humanos contra el estrés oxidativo . Los compuestos fe nólicos son los principales antioxidantes en lechuga y bajo condiciones de creci miento con limitaciones, puede modificarse la cantidad y composición de éstos (Ouhibi et al, 2014). En situaciones de crecimiento adversas, como el riego con agua con alto contenido de sales, cuyo efecto sobre el crecimiento en varios genoti pos no es importante, puede implicar una mejora en la ca pacidad antioxidante, y ser utilizada como una estrategia o práctica de cultivo para au mentar el contenido de fito químicos en lechuga mejorando el valor funcional de este alimento ).…”

RESUMENLa producción hortícola en la zona de Santa Rosa, La Pampa, se realiza bajo riego, el agua dis ponible para tal fin tiene un alto contenido de sales. El objetivo de este trabajo es evaluar la res puesta del crecimiento, la actividad de la SOD y la concentración de malondialdehido, al riego con agua salina en 11 genotipos de lechuga. Se trabajó en invernáculo, y los plantines durante 54 días fueron regados con dos calidades de agua, de lluvia y con alta salinidad. Los genotipos Grand Rapid, Bermella y Boltar mostraron una reducción del peso seco del 12, 11 y 87% respectivamente y en Grand Rapid e Ice 15975 la reducción del vigor fue del 3 y 2% respectivamente. En Ice 15975, Gran Rapid y Bermella hubo un incremento de la concentración de malondialdehido del 98, 138 y 56% respectivamente ante el riego con agua salada. En Ice 15975 y Grand Rapid esta respuesta se asocia a una disminución de la actividad de la SOD. El resto de los genotipos no expresó cam bios en la concentración de malondialdehido. Estos resultados evidencian una respuesta diferencial de los genotipos en estudio, y la concentración de malondialdehido puede usarse para seleccionar genotipos de lechuga tolerantes al riego con agua con alto contenido de sales al estado de plantines. ABSTRACTHorticultural production is carried out under irrigation in the area of Santa Rosa, La Pampa pro vince, where available water sources are highly concentrated in salts. The aim of this study was to evaluate the effect of irrigation with high salt content water on growth, superoxide dismutase (SOD) activity and malondialdehyde concentration, in seedlings of 11 lettuce genotypes. The experiment was performed in a greenhouse, where the seedlings were irrigated for 54 days with two different kinds of water, one from rain as a control and another one of high salinity. Irrigation with high salinity water caused a decrease of 11, 12 and 87% in dry weight yield for Bermella, Grand Rapid and Boltar genotypes, respectively, and a vigor reduction of 2% for Ice 15975 and 3% for Grand Rapid. A the same time, irrigation treatment with high salinity resulted in plant malondialdehyde concentration in creases of 56, 98 and 138% for Bermella, Ice 15975 and Grand Rapid, respectively. In the case of the last two genotypes, their response was associated with a SOD activity decrease. The rest of the genotypes did not show changes in malondialdehyde concentration. These results evidenced a dif ferential response among the assayed lettuce varieties, and that malondialdehyde concentration can Recibido 23/. 2017.
