To study the antioxidant capacity of the exopolysaccharides peptides (EPSP) from Ganoderma lucidum, four methods including 1,1-diphenyl-2picrylhydrazyl (DPPH) radical scavenging assay, reducing power assay, self-oxidation of 1,2,3-phentriol assay and hydroxyl radical assays were employed in vitro. The sample demonstrated scavenging capacity in a dose-dependent manner in every assay. Among them,...

The antioxidant activities of the various extracts and fractions from the herbs of Artemisia selegensis Turcz (AST) were investigated by in vitro and in vivo assays. FRAP, DPPH and ABTS assays were used to evaluate the antioxidant activities of the extracts/fractions in vitro. The effect of water extract (WE) in reducing oxidative stress in male mice was evaluated. Phenolic acid compounds contr...

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...

The present study was carried out to evaluate the antimicrobial and antioxidant activities of methanol extract of Careya arborea (MECA) stem barks (Myrtaceae) in various in-vitro systems. Antimicrobial activities of MECA were carried out using disc diffusion methods with Gram positive and Gram negative bacteria and some fungal species. MECA showed broad-spectrum antimicrobial activity against a...

Reacting active species induced oxidative damage of cellular tissue cause to many human diseases like cancer, cardiovascular disease, nephropathy and aging. Naturally occurring antioxidant supplements from plants are vital to counter the oxidative damage in cells. Recently, attention has focused on phytochemicals as new sources of natural antioxidants. Therefore, the main objective of the prese...

the antioxidant potential of crude methanol extract (ce) as well as chloroform (cf), ethyl acetate (ef) and n-butanol (nf) soluble fractions of enhydra fluctuans lour, which is widely used in indigenous system of medicine for different purposes, were studied. the antioxidant potential of extract/different fractions were evaluated using different in vitro antioxidant models. in addition, total a...

The present work describes the isolation of α - and β -carotene from crude palm oil and their antioxidant potential in an in vitro model. Pure product was isolated by the method adopted. Antioxidant activities of the isolated α - and β -carotene were analyzed in five different concentrations of 0.001, 0.005, 0.01, 0.05, and 0.1% (w/v). From the several assays conducted, an observation was made ...

We evaluated the antioxidant properties of four main flavones from Scutellaria baicalensis: baicalein, wogonin and their glucuronides - baicalin and wogonoside. We used three in vitro assays: free radical scavenging with 2,2'-diphenylpicrylhydrazyl radical, transition metal ions reducing power by phosphomolybdenum assay and inhibition of the hydroxyl radical-induced peroxidation of linoleic aci...

Lantadenes are pentacyclic triterpenoids present in the leaves of the plant Lantana camara. In the present study, in vitro antioxidant activity and free radical scavenging capacity of lantadene A was evaluated using established in vitro models such as ferric reducing antioxidant power (FRAP), 2,2-diphenyl-1-picryl-hydrazyl (DPPH•), hydroxyl radical (OH•), nitric oxide radical (NO•), superoxide ...

Terminalia bellerica Roxb. (Family: Combretaceae) has been valued in Indian system of medicine for treatment of wide range of diseases and reported to have antioxidant properties. In the present study, the free radical scavenging activity and antioxidant potential of acetone extract/fractions of its fruit was investigated using in vitro assays, including scavenging ability against 2,2'-diphenyl...
