One of the most reactive and dangerous agents for the living cells is reactive oxygen free radical species (ROS). When there is an imbalance between ROS generating and scavenging systems (oxidative stress), tissue damages will appear in human body such as degenerative disorders of CNS like Alzheimer's disease. Recently, a high interest in medicinal plants containing antioxidants has been increa...

The plant is a potential source of valuable nutrients that is valued for human food. The fruit of this plant, being a rich source of high-value components, is usually pickle...

in order to evaluate the effect of different concentrations of postharvest salicylic acid and calcium chloride on shelf life, quality characteristics and antioxidant activity of peach fruit cv. amesden, an experiment was conducted as factorial based on randomized completely design with three replications. fruits were harvested at the commercial ripening stage, and fruits were immerged in differ...

the objective of this study was to evaluate the storage life and quality of persimmon (diospyros kaki thunb.) fruit cv. ‘karaj’ stored at 0°c for 4 months after postharvest calcium chloride treatment. fruit weight loss, fruit firmness, total soluble solids, titratable acidity, total phenolic content, soluble tannin content, chilling injury, antioxidant activity, electrolyte leakage, and malondi...

drought, withnegative impacts on plant growth and development, isa major abiotic stress. in order to decreasing drought stress injuries and recognizing red peppers tolerance physiology against drought stress in greenhouse conditions, an experiment with three levels of drought stress (irrigation at 100, 60 and 30% of field capacity) and four concentrations of 5-aminolevolinic acid ((ala; 0, 0.25...

Barberry fruit is consumed in different forms including dried fruit, juice, jam and marmalade in Iran. This fruit is also used as a food additive (flavoring and colorant) in soup and rice dishes. In present study, antioxidant activities of acetone, ethanol and water (infusion and decoction) extracts of barberry (Berberis vulgaris) fruit were investigated using 2,2-azinobis-3-ethylbenzo...

abstract: in a wide search program towards new and efficient antimicrobial agents, a series of 4-substituted-1,2,4-triazolidine-3,5-dione derivatives namely urazoles holding an alkyl moiety at position 4 have been synthesized and tested for their in vitro antibacterial and antifungal activities. the structures of these compounds have been investigated by spectral data. the synthesized compounds...

The effects of postharvest oxalic acid (OA) treatment on ethylene production, fruit quality, bioactive compounds and antioxidant activity of peach fruit, were examined. Fruits were treated with oxalic acid immediately after harvest and stored at 1° C and 90% relative humidity for 28 days. The oxalic acid treated peach fruit exhibited significantly lower levels of ethylene production, pH, total ...

in this study, antioxidant activity of kolkhung skin oil, baneh skin oil and seasame oil were compared. the ratio between polyunsaturated to saturated fatty acids (pufa/sfa) of kolkhung skin oil, bane skin oil and seasame seed oil were 0.52, 0.26 and 3.06, respectively. total phenolic contents of kolkhung skin oil, bane skin oil and seasame seed oil were 99.67, 645.73 and 81.72 mg/kg, respectiv...
