Abstract. Green extraction method by combination of stirring with no presence heat and the use aqueous as solvent were highlighted in this study. Various solvents (aqueous, chloroform, ethyl acetate, hexane methanol) two methods (stirring Soxhlet) used to study their effect on yield, qualitative phytochemical content, antioxidant properties Diplazium esculentum Retz. Stenochlaena palustris. Sti...

The main intrest of this study was to evaluate the antihemolytic and antioxidant activities aqueous extracts Globularia alypum Zygophyllum album prepared by three different methods: decoction, infusion maceration. Phytochemical tests, total phenolic, flavonoid tannins contents were determined. DPPH radical scavenging assay Ferric Reducing Antioxidant Power (FRAP) employed for evaluation activit...

In present study, the anthocyanin composition and content of the fruit of B. heteropoda Schrenk were determined for the first time. The total anthocyanins were extracted from the fruit of B. heteropoda Schrenk using 0.5% HCl in 80% methanol and were then purified using an AB-8 macroporous resin column. The purified anthocyanin extract (PAE) was evaluated by high-performance liquid chromatograph...

The antioxidant activity of Syzygium cumini leaf extracts was investigated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical-scavenging and ferric-reducing antioxidant power (FRAP) assays. The methanolic extract and its four water, ethyl acetate, chloroform, and n-hexane fractions were prepared and subjected to antioxidant evaluation. The results showed that the ethyl acetate fraction...

Ethanol extract of ginger, turmeric and cinnamon was assessed for its antioxidant, antimicrobial and antiinflammatory activity. The antioxidant activity was determined by measuring FRAP (ferric reducing-antioxidant power) assay. The antibacterial efficacy was determined using paper disc method against different gram negative bacterial and sensitivity in terms of zones of inhibition of all extra...

In this study we investigated the effects of Caesalpinia decapetala (CD) extracts on lipid oxidation in ground beef patties. Plant extracts and butylated hydroxytoluene (BHT) were individually added to patties at both 0.1% and 0.5% (w/w) concentrations. We assessed the antioxidant efficacy of CD by the ferric reducing antioxidant power (FRAP) assay and evaluated their potential as natural antio...

BACKGROUND Asparagopsis taxiformis (Rhodophyta) is a species of red algae belonging to the family Bonnemaisoniaceae. The objective of the present study was to evaluate antioxidant and antiproliferative activity of four fractions (petroleum ether, chloroform, ethyl acetate, and methanol) of A. taxiformis. MATERIALS AND METHODS The red seaweed, A. taxiformis was collected from Mandapam Coastal ...

BACKGROUND Decoction prepared from leaves of Atalantia ceylanica is used in traditional medicine in Sri Lanka for the treatment of various liver ailments since ancient times. Lyophilized powder of the water extract of A. ceylanica leaves was investigated for its phytochemical constituents, antioxidant and hepatoprotective activity in-vitro. METHODS The total phenolic and flavonoid contents we...

The growing interest on the replacement of synthetic antioxidants with natural ones has directed many research toward the plant-derived raw materials. The special attention is focused on inexpensive or residual sources from food agricultural industries. Fruit peels are valuable wastes obtained from domestic and industrial sources. The potential of fruit wastes as sources of natural antioxidants...

bioactive food components (such as phenolic compounds, carotenoids, anthocyanins, tochopherols, ascorbic acid, flavonoids, minerals, enzymes and pectin) are active ingredients in food or dietary supplements, which proven to have an important role in health, and are safe for human consumption. these compounds exert their antioxidant effects by different mechanisms such as single electron transfe...
