Chronic neuroinflammation and oxidative stress contribute to the neurodegeneration associated with Alzheimer's disease and represent targets for therapy. Ferulic acid is a natural compound that expresses antioxidant and anti-inflammatory activities. Nitric oxide is also a key modulator of inflammatory responses. Grafting a nitric oxide-releasing moiety onto anti-inflammatory drugs results in en...

Terminalia bellirica Roxb belongs to the family Combretaceae, is distributed throughout the deciduous forests of India. The petroleum ether, chloroform, ethanol and aqueous extracts of the bark of Terminalia bellirica were screened for free radical scavenging activity against DPPH, ABTS, superoxide, nitric oxide, hydroxyl and hydrogen peroxide radicals. The scavenging activity was found to be d...

abstract   anthocyanins are natural pigments widely spread in nature. anthocyanin color molecules are a subclass of flavonoids. they are responsible for red, purple, and blue colors of many flowers, fruits and vegetables. fruits and berries are sample sources of anthocyanins in nature. in many researches, the positive effects of fruits and berries intake on human health have been reported. anth...

The present study aims to investigate the phytochemical profiles, in vitro antioxidant and antiproliferative properties of methanol 70% ethanol extracts Camellia mistletoe. Both were analyzed for contents total flavonoid, carotenoid L-ascorbic acid, such as scavenging capacities (1,1-diphenyl-2-picrylhydrazyl, O2- NO), ferrous ion chelating reducing power. MTT assay was used assess against huma...

The aim of this study was to evaluate the probiotic properties lactic acid bacteria (LAB) isolated from kimchi and antioxidant anti-inflammatory activities heat-killed LAB strains. Regarding properties, Lactiplantibacillus plantarum SMF398 L. SMF470 can survive under artificial gastric condition adhere strongly HT-29 cells. strains showed strong antimicrobial activity co-aggregation against pat...

The antioxidant action of ethanolic extract from Agaricus bisporus which is available in the supermarkets of Bucharest, Romania, was assessed by determining its reducing power and its radical scavenging activity. The determinations were made by analyzing the freeze-dried ethanolic extract. The radical scavenging activity was determined using 2, 2-diphenyl-1-picrylhydrazyl (DPPH), superoxide rad...

In the present study, coarse powder of Scindapsus officinalis (Roxb.) Schott. fruit was extracted successively using hexane, chloroform, ethyl acetate and 50% ethanol. The ethyl acetate and 50% ethanolic extracts were investigated for its antioxidant activity by using nitric oxide and DPPH radical scavenging methods. The IC value was also calculated. Ascorbic acid was used as standard. Both the...

A series of 3,4-dihydroisoquinoline-3-carboxylic acid derivatives were synthesised and tested for their free-radical scavenging activity using 2,2-diphenyl-1-picrylhydrazyl radical (DPPH·), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical (ABTS·+), superoxide anion radical (O2·-) and nitric oxide radical (·NO) assays. We also studied d-amino acid oxidase (DAAO), acetylcholinestera...

The aim of this research is to study the synergistic effect on nitric oxide scavenging activity mangosteen pericarp and stingless bee (Tetragonula laviceps) propolis extracts their phytochemical constituents. were extracted by reflux method with ethanol. TPC TFC extract 123.73±2.80 mg GAE/g 70.65±11.21 QE/g extract, respectively, was 387.93±15.10 87.00±5.06 respectively. ESI-LC-MS data displaye...
