PURPOSE The paper tried to systematically investigate the in vitro antioxidant activity of Rhizoma Cibotii (RC) for the first time. METHOD The methanol extract from RC (MERC) was prepared then systematically investigated by various antioxidant assays, including: DPPH• (1, 1-diphenyl-2-picrylhydrazyl radical), ABTS•(+) (3-ethylbenzthiazoline-6- sulfonic acid diammonium salt radical), •O2- (sup...

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 ...

Hemp protein hydrolysates with various yields of trichloroacetic acid (TCA)-soluble peptides (Ysp) and surface hydrophobicity (Ho) were obtained by Neutrase ® hydrolysis from hemp protein isolate (HPI). The peptide profiles, amino acid composition and antioxidant activities (DPPH radical scavenging ability, reducing power and Fe chelating ability) of the hydrolysates, obtained at 60–240 min, we...

the antioxidant and cytotoxic properties of four major parts of methanolic extracts of tephrosia purpurea including leaves, root, stem and seed were investigated and compared. in vitro antioxidant activity of t. purpurea extracts was evaluated using 1,1-diphenyl-2-picrylhydrazyl (dpph), ferric reducing antioxidant power (frap), reducing power assay and antihemolytic assay. in vitro cytotoxic ef...

Ethanol extracts of Piper aduncum L. leaves from five sub-regions in the tropical Peruvian rainforest were assessed for polyphenol content utilizing liquid chromatography coupled with mass spectrometry with electrospray ionization (LC-MS-ESI). The anti-oxidant capacity was estimated using a DPPH radical scavenging assay. Additionally, the reducing power (capacity to reduce Fe 3+ to Fe 2+ ), the...

Antioxidant potential of various extracts of Cassia fistula was determined by the DPPH, FRAP, Fe(3+) reducing power, and hydrogen peroxide scavenging assay. Methanolic extracts of Cassia fistula showed the highest amount of phenolic and flavonoid content and reducing capacity, whereas hexane extracts exhibited the lowest level of reducing capacity. The order of antioxidant activity in Cassia fi...

background: the approaches chosen for control of outbreaks of infectious diseases in aquatic farming industry include improvement of environmental conditions, stocking of specific pathogen free (spf) brood stockings, and application of vaccines and immunostimulants. despite numerous studies on the effects of ergosan on immune system of aquatic animals, there is no data available on antioxidant ...

Soil has been used to generate electrical power in microbial fuel cells (MFCs) and exhibited several potential applications. This study aimed to reveal the effect of soil properties on the generated electricity and the diversity of soil source exoelectrogenic bacteria. Seven soil samples were collected across China and packed into air-cathode MFCs to generate electricity over a 270 days period....
