The antioxidant activity of extracts from bark and heartwood of Acacia confusa was evaluated by various antioxidant assays, including free radical and superoxide radical scavenging assays and lipid peroxidation assay as well as hydroxyl radical-induced DNA strand scission assay. In addition, an ex vivo antioxidant assay using a flow cytometric technique was also employed in this study. The resu...

Commercially available analytical kits for the estimation of total antioxidant status are expensive and time-consuming. Most of the commercially available kits for total antioxidants estimation are based on the principle of suppression of ABTS radical cation formation by antioxidant in the serum sample. The method requires stringent assay conditions, like exact incubation time and the temperatu...

In the present study, antioxidant potential of the different extract of the whole plant of Aerva tomentosa Forsk. was evaluated by using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) scavenging assay and total phenolic contents was analyzed using the Folin-Ciocalteu reagent method. The methanol extract showed significant activity in antioxidant assay compared to other successive extracts such as peteth...

The ethanol extracts of Datura stramonium and Datura metel (Family: Solanaceae) collected from Pappakovil, Nagapattinam Dist of Tamil Nadu, India. The Ethanol extract obtained by maceration extraction was examined for its antioxidant activities. The antioxidant activity was determined by means of the DPPH radical scavenging test, Total antioxidant (TAA) and superoxide anion scavenging activity ...

Background & Aim:Extracts of Roselle calyx,   possess compounds which could be considered as a great source of natural antioxidants.   In this project, antioxidant activities, phenolic compounds content and their   correlation analysis on calices of Roselle (Hibiscus sabdariffa) was investigated.  Experimental: Total polyphenolic compound, flavonoids and anthoc...

In this study, n-butanol fraction (KBF) and aqueous fraction (KAF) isolated from methanol extract of Koelreuteria paniculata Laxm. leaves were evaluated for their antioxidant potential using (ABTS) 2, 2-Azino-bis-(3-ethylbenzthiazoline-6-sulfonic acid), DPPH (2,2-diphenyl-2-picrylhydrazyl) assay, Reducing power assay and Superoxide anion radical scavenging assay. These fractions were also studi...

BACKGROUND The emergence of drug resistant malaria is threatening our ability to treat and control malaria in the Southeast Asian region. There is an urgent need to develop novel and chemically diverse antimalarial drugs. This study aimed at evaluating the antimalarial and antioxidant potentials of Acacia nilotica plant extracts. METHODS The antioxidant activities of leaves, pods and bark ext...

Oxidative stress can damage cellular components including DNA, proteins or lipids, and may cause several skin diseases. To protect from this damage and addressing consumer's appeal to natural products, antioxidants obtained from algal and vegetal extracts are being proposed as antioxidants to be incorporated into formulations. Thus, the development of reliable, quick and economic in vitro metho...

In the present study, antioxidant potential of the methanol extract of the leaves of Mimusops elengi Linn. was evaluated by using 1, 1-diphenyl-2-picrylhydrazyl (DPPH) scavenging assay, reducing power and total antioxidant capacity. The extract showed significant activities in all antioxidant assays compared to the reference antioxidant ascorbic acid in a dose dependent manner. In DPPH scavengi...
