Objective: In this study, the levels and antioxidant activities of some secondary metabolites isolated from five pistachio (Pistacia vera)cultivars collected from four different geographical regions of Iran, were studied. Materials and Methods: Total phenolic compounds levels were determined by Folin-Ciocalteu method. Total flavonoid content was determined as AlCl3 complex and expressed as mg o...

In order to investigate the effects of water stress on total phenolics content, antioxidant power, β-glucosidase activity and stomatal properties of alfalfa, a factorial experiment based on randomized complete block design was carried out in 1-Lit pots containing half strength Hoagland culture medium using two cultivars of alfalfa at four osmotic pressures including 0 (control), -0.5, -1.0 and ...

Background: Cornus sanguinea L subsp australis (C.A. Mey.) Jáv. (Cornaceae) is a native species in north and northwest of Iran. It is locally named Siah-al. The genus Cornus is rich source of anthocyanins. Objective: In this study the antioxidant activity, total phenol and total anthocyanin contents of different extracts of C. sanguinea L subsp australis. were investigated for the first time. ...

Processed fruits and vegetables have been long considered to have lower nutritional value than the fresh produce due to the loss of vitamin C during processing. Vitamin C in apples has been found to contribute <0.4% of total antioxidant activity, indicating most of the activity comes from the natural combination of phytochemicals. This suggests that processed fruits and vegetables may retain th...

the effect of different concentration of salicylic acid (0, 1 and 2 mmoll-1) and chitosan (0, 0.5 and 1 percent) on postharvest life and quality of selva strawberry fruit during storage at 2.5±0.5°c with 85-95% rh for 7 and 14 days was studied. decay incidence, marketability, total soluble solids, total acidity, vitamin c content and total antioxidant activity were evaluated during storage. chi...

honey is a popular food product produced by honey bees that it is a well-known antimicrobial and antioxidant activity. floral origin of honey plays an important role on its biological properties.this research was carried out to evaluate the antibacterial and antioxidant activity of four sample honey with different floral origin collected from the bee hive in the golestan province in north of ir...

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...
