Pyrrolidine dithiocarbamate (PDTC) is considered an antioxidant and is frequently used to study the role of free radical reactions in various biological processes and against free radical-induced cellular injuries. However, its antioxidant properties are not characterized. In this study, electron spin resonance (ESR) was used to investigate the antioxidant potential of PDTC with hydroxyl radica...

salvia leriifolia benth. from lamiaceae family is a plant native to iran and afghanistan with significant applications in medical, pharmaceutical and food industries. the aim of current investigation was to evaluate the composition and antioxidant activity of essential oils (eos) of s. leriifolia growing naturally in neyshabur and bajestan (northeast of iran). the aerial parts of the plant were...

Microwaves and ultrasonic extraction methods are promising techniques that can be used for this purpose. OBJECTIVES The purpose of this study was to investigate the impact of different extraction methods on yield, antioxidant and antimicrobial activities of volat...

Scutellaria is widely used in traditional medicine as a medical plant, in Asian countries, especially in China. It has been applied in treatment because of its sedative, antithrombotic, anti-inflammatory, antioxidant, and antiviral effects. Scutellaria condensata Rech. f. subsp. pycnotricha (Rech. f.) Rech. f. is a wild perennial plant which  grows in Iran. In this study, GC-FID and GC-MS were ...

conclusions the results of the present investigation suggest that sac could be used as a food supplement in the treatment of diabetes characterized by provoked antioxidant status, altered blood glucose, and hormones level. results the levels of glucose, cyp2e1 activity, thiobarbituric acid reactive substances (tbars), hydroperoxide, and ceruloplasmin were increased significantly; whereas, the l...

background: recent studies have shown that oxidative stress (os) is the most important indicator in the pathogenesis of alzheimer's disease (ad), but the results in previous studies are conflicting. this study aimed to assess the plasma levels of 8-hydroxy-2'-deoxyguanosine (8-ohdg) as dna oxidative damage marker and total antioxidant capacity (tac) in patients with ad versus control ...

Antioxidant activities of Satureja boissieri extracts were detected by using specific in vitro techniques. Standard antioxidant compounds such as ascorbic acid, BHA (Butylated Hydroxyanisole) and BHT (Butylated Hydroxytoluene) were used to compare with the results obtained from ethanol and water extracts of the plant samples. Both extracts presented high antioxidant <span ...

BACKGROUND Hyperthyroidism is associated with liver oxidative stress causing liver dysfunction in many hyperthyroid patients. The hepatoprotective effect of Satureja Khuzestanica Essential Oil (SKEO), as herbal origin antioxidant and anti-inflammatory agent on the hyperthyroidism induced hepatotoxicity and oxidative stress is investigated. METHODS Adult male sprague dawley rats were divided i...

background and aims. the antioxidant and anti-inflammatory properties of propolis were studied. since saliva contains antioxidants and radiotherapy of the head and neck mainly affects the saliva, salivary antioxidant defensive mechanism is compromised with oxidative stress produced by radiation therapy. therefore, the aim of the present study was to investigate the effect of propolis on salivar...
