The antioxidant activities of crude extract of Phaulopsis fascisepala leaf were evaluated and compared with alpha-tocopherol and BHT as synthetic antioxidants and ascorbic acid as natural-based antioxidant. In vitro, we studied its antioxidative activities, radical-scavenging effects, Fe(2+)-chelating ability and reducing power. The total phenolic content was determined and expressed in gallic ...

A total of fourteen (14) species of wild edible fruits from Burkina Faso were analyzed for their phenolic and flavonoid contents, and their antioxidant activities using the DPPH, FRAP and ABTS methods. The data obtained show that the total phenolic and total flavonoid levels were significantly higher in the acetone than in the methanol extracts.Detarium microcarpum fruit had the highest phenoli...

This work was undertaken to explore antityrosinase and antioxidant activities of twenty essential oils of edible Thai plants. Antityrosinase activity against mushroom tyrosinase was examined by means of the dopachrome method using L-dopa as an enzymatic substrate. The essential oil of Cymbopogon citratus had the highest level of antityrosinase activity, followed by that of Ocimum canum with enz...

Seasonal discrepancy in the antioxidant potential from bark of Nothapodytes nimmoniana was evaluated using two different methods (DPPH and FRAP) and were related to total phenolic content as well as flavonoid content. Higher yield of phenolic and flavonoid were observed during summer (May) similarly, the antioxidant activities (DPPH & FRAP) also were high. The antioxidant activities were strong...

Commiphora molmol oleoresin (Family Burseraceae) is traditionally used for treatment of many ailments such as ulcers, abscesses and wounds. The aim of this study was to evaluate the antimicrobial and antioxidant activities of C. molmol extracts in vitro (essential oils and ethanol extract). The antimicrobial activities of extracts were evaluated by disc diffusion and micro-broth dilution assays...

the present study investigated the effects of e. coli lipopolysaccharide (lps) induced mastitis model in rat on the activity of antioxidant enzyme systems. to achieve this purpose, e. coli lps were infused into the mammary gland of 12 rats 72 hr postpartum and compared with 12 rats in control group infused intramammary placebo sterile pyrogene – free, physiological saline. the antioxidant activ...

Withania somnifera an Indian traditional medicinal herb, is known to possess antistress, antioxidant, analgesic, anti-inflammatory, cardioprotective, adaptogenic, antispasmodic, immunomodulatory and immunostimulant activities. Its other activities include anti-inflammatory, immunoregulatory, anti-tumor, anti-angiogenic, antiinvasive and chemopreventive effects. We investigated the antioxidant, ...

The present study was aimed at investigating the antioxidant activities of the various fractions of the hydromethanolic extract of the leaves of Coccinia grandis L. Voigt. (Cucurbitaceae). The antioxidant activities of the fractions have been evaluated by using nine in vitro assays and were compared to standard antioxidants such as ascorbic acid, alpha-tocopherol, curcumin and butylated hydroxy...

Antioxidant capacities of ethylacetate, butanol, and water fractions of peel, pulp, and seeds of Canarium odontophyllum Miq. (CO) were determined using various in vitro antioxidant models. Ethylacetate fraction of peel (EAFPE) exhibited the highest total phenolic (TPC), total flavonoid content (TFC), and antioxidant activities compared to pulp, seeds, and other solvent fractions. Antioxidant ca...

PURPOSE This research paper presents antioxidant and antimicrobial activities of Pedicularis sibthorpii and Pedicularis wilhelmsiana which grow in Azerbaijan/Iran with claimed a lot of therapeutic effects. METHODS DPPH assay and agar well diffusion method were carried out to determine antioxidant and antimicrobial activities respectively. RESULTS Methanolic extract showed better antioxidant...
