The study was aimed to evaluate the antioxidant activity of Cassytha filliformis for the first time. The antioxidant activity of cassytha filiformis extracts in hexane, ethyl acetate and methanol were assessed based on their radical scavenging activity (RSA) using the DPPH assay. Methanolic extract showed good antioxidant activity when compared with standard Butylated hydroytoluene(BHT). Furthe...

BACKGROUND/OBJECTIVE This study aims to measure the in vitro antioxidant capacity of Korean diet (KD) with American diet (AD) as a control group and to examine the ex vivo DNA damage reduction effect on human lymphocytes. MATERIALS/METHODS The KD applied in this study is the standard one-week meals for Koreans (2,000 kcal/day) suggested by 2010 Dietary Reference Intakes for Koreans. The AD, w...

Most of the world’s populations residing in developing countries depend on alternative medicine and use of plant ingredients. Caesalpinia pulcherrima (Fabaceae) is used in folk medicine for the treatment of various diseases including asthma, bronchitis, cholera, diarrhea, dysentery and malarial infection. The present study was undertaken to determine antimicrobial, antioxidant and cytotoxic act...

background and objectives:scrophularia variegata m. beib. (scrophulariaceae) is a medicinal plant, used for various inflammatory diseases in iranian traditional medicine. in the present study, we evaluated the immune modulation and antioxidant effects of the hydroalcoholic extract of s.  variegata. methods: the splenocytes were harvested from the spleen of balb/c mice and were cultured. the spl...

Various methods employed in evaluating antioxidant activities of various samples gives varying results depending on the specificity of the free radical or oxidant used as a reactant. This study investigated the antioxidant /radical scavenging properties of the methanolic extract of Vernonia amygdalina (MEVA) leaves and studied the relationship between the assay methods. Antioxidant capacity of ...

This study investigated the effect of dry heat on the antioxidant capacity of water extracts of six spices, namely black pepper (Piper nigrum Linn.), cumin (Cuminum cyminum Linn.), clove (Syzygium aromaticum Linn.), cinnamon (Cinnamomum verum, syn. C. zeylanicum Blume), sumac (Rhus coriaria L.) and golpar (H. persicum Desf. Ex.), which were either roasted or heated in a microwave oven, powdered...

OBJECTIVE Allium elburzense is an endemic plant of the family Amaryllidaceae that grows wild in northern Iran with some nutritional and medicinal applications. The present study was aimed to investigate the fibrinolytic and antioxidant effects of A. elburzense bulb extracts. MATERIALS AND METHODS Hydroalcoholic, aqueous, chloroformic and butanolic extracts were evaluated in this research. In ...

 Background: The use of natural products as anticancer and antioxidant agents has a long history. Several drugs currently used in chemotherapy were isolated from plant species. Objective: The aim of this study was to evaluate cytotoxicity and antioxidant activity as well as phenol and flavonoid contents of five plant species of Solanaceae family. Methods: Five plant species of Solanace...

The fungi are an exceptionally useful model in elucidating the cell functions under extreme conditions (temperature, salinity, pH values) and mechanisms underlying adaptation to those extreme environmental conditions. Here, Chaetomium globosum was examined for its adaptation mechanism under alkaline stress using antioxidant properties. The aqueous extracts of C. globosum exhibited different lev...

The in vitro total antioxidant assay, total phenolic content, DPPH assay, FRAP assay of the acetone extracts from four centric diatoms (Chaetoceros simplex, Skeletonema costatum, Odontella mobiliensis, Coscinodiscus centralis) and three pennate diatoms (Nitzschia closterium, Pleurosigma angulatum and Navicula sp.) were performed. The centric diatom, O. mobiliensis was found higher amount of phe...
