the essential oil from the aerial parts ofjurinea leptoloba dc., collected from shiraz (south of iran), was investigated for total phenolic content (tpc), antioxidant and cytotoxic effects. tpc of j. leptoloba oil was determined to be 16.53 ± 5.69 μg gallic acid equivalent/mg sample (μg gae/mg oil) using the folin-ciocalteau assay. the ferric reducing power of the oil was determined 0.117 ± 0.0...

objective: antioxidants are considered as the main factors in the inhibition of unwanted oxidation reactions. materials and methods: in this research the antioxidant potential of the fresh fruits of 4 cultivars (a to d) of malus domestica (m. domestica) cultivated in the kashan, qamsar area was evaluated. the antioxidant activity of the samples were evaluated using two complementary antioxidant...

To obtain a better understanding of the mycorrhizas as an elicitor, and precursor feeding effects on the protein content and TIAs biosynthesis in Catharanthus roseus L., foliar application of four concentrations of tryptophan (0, 150, 250 and 350 mg/l) on some growth parameters and chemical compositions of mycorrhizal plants were investigated. The results revealed that the total protein content...

in the present study, we have reported the total phenolic content, total flavonoid content, antioxidant and antimicrobial activity of aerial parts of salvia leriifolia extracts and fractions. methanolic, n-hexane, chloroform, and ethyl acetate extracts were screened to analysis their antioxidant activities by four complementary test systems, namely dpph free radical scavenging activity (rsa), t...

meningitis is one of the most common infectious cerebral nervous system (cns), defined as an inflammation of the meninges. it is clinically categorized into a chronic and acute based on the acuity of symptoms. vomiting, bulging fontanel and fever are the main symptoms in the patients with meningitis. bacterial meningitis is a severe, potentially life-threatening infection that is associated wit...

cottonseed is considered among most important crops. it contains about 26 percent oil that ‎in used for vegetable oil production. after oil extraction, the remaining part of the seed know as ‎cottonseed cake with 45 percent protein is routinely used as a protein supplement in feed ‎rations for livestock and less for food use due to presence of gossypol, a toxic constituent of ‎cottonseed.‎ in t...
