The effect of aqueous extract of Loranthus micranthus on the kidney of albino rat induced with Lead acetate on catalase activity, nitric oxide scavenging (NOS) activity and total protein was investigated. 30 albino rats were used and they were divided into 6 groups. 200 mg/kg of lead acetate was injected intraperitoneally into the rats to intoxify and the extract was administered orally as a th...

Smilax glabra Roxb. has been used for a long time as both food and folk medicine. In the present study, phenolic-enriched extract of S. glabra (PEESG) was extracted with 70% ethanol and purified by HP-20 column chromatography. Its antioxidant and anti-inflammatory activities were evaluated by radical scavenging assay, reducing power determination, and lipopolysaccharide (LPS)-induced RAW264.7 c...

OBJECTIVE To analyze the total phenolic content, DNA protecting and radical scavenging activity of ethanolic leaf extracts of three Lamiaceae plants, i.e. Anisomelos malabarica (A. malabarica), Leucas aspera (L. aspera) and Ocimum basilicum (O. basilicum). METHODS The total polyphenols and flavonoids were analyzed in the ethanolic leaf extracts of the lamiaceae plants. To determine the DNA pr...

Aim:The present study aimed to assess the in vitro antioxidant and anticancer properties of Drosera peltata J.E.Sm. Methods:Antioxidant capacity of the extracts were tested on hydroxyl, DPPH, super oxide, nitric oxide and ABTS radicals; of ferrous ion chelating ability and by reducing power assay.Ascorbic acid was used as the standard antioxidant for the above all assay methods. Dalton’s Asciti...

Background: Naringenin is a bioactive flavonoid found in grapes and citrus fruits including tangelo, blood orange, lemons, and tangerines. The aims of this study were to investigate the ability of naringenin to scavenge free radicals and determine its ability to protect animals from streptozotocin (STZ) -induced liver damage. Methods: The free radical-scavenging activity of naringenin was ev...

The fruit of Euterpe oleraceae, commonly known as acai, has been demonstrated to exhibit significantly high antioxidant capacity in vitro, especially for superoxide and peroxyl scavenging, and, therefore, may have possible health benefits. In this study, the antioxidant capacities of freeze-dried acai fruit pulp/skin powder (OptiAcai) were evaluated by different assays with various free radical...

nitric oxide is a short-lived mediator, which can be induced in a variety of cell types and produces many physiologic and metabolic changes in target cells. it is important in many biological functions and generated from l-arginine by the enzyme nitric oxide synthase. nitric oxide conveys a variety of messages between cells, including signals for vasorelaxation, neurotransmission and cytotoxici...

BACKGROUND Rhododendron anthopogonoides Maxim, a kind of traditional Tibetan medicine, has been used to remove body heat, body detoxification, cough, asthma, stomachic and swelling, eliminate abundant phlegm and inflammatory for a long time. In the present study, the total phenols and total flavonoid contents as well as antioxidative properties of the crude extract and solvent fractions of R. a...

The main objective of this study is to evaluate the anti-oxidant properties in methanolic extract of Leaves and fruit of cucumies melo () The methanol leaf extract noticed significant scavenging activity on DPPH, superoxide, nitric oxide , hydrogen peroxide and hydroxyl radical. The total phenolic compounds were found to be high with leaves rather than the flesh of fruit.
