UNLABELLED BACKGROUND This study aims to determine the relationship between the antioxidant and anti-inflammatory activities of the thirteen herbs and two fungi extracts, and their total phenolic and flavonoid contents. METHODS Antioxidant activities were evaluated by four assays: an antioxidant activity assay using Saccharomyces cerevisiae, a DPPH ((2, 2-diphenyl-1-picrylhydrazyl) assay t...

Total phenolic contents (TPC) of five different extracts (petroleum ether, dichloromethane, ethyl acetate, ethanol and ethanol-water) of Artemisia biennis Willd were measured in this work. The antioxidant activity was investigated by three different methods: β-carotene bleaching (BCB) test, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method and ferrous ion chelating (FIC) assay. Amo...

This study aimed to obtain and characterize extracted hemp oil enriched in cannabidiol (CBD) by decarboxylation of cannabidiolic acid (CBDA) give new insights into its antioxidant anticancer effects. Optimization CBDA was performed, CBD contents purities were determined flash chromatography, 1H- 13C-NMR. The properties CBD-enriched investigated Fe2+ chelating activity, Fe3+ reducing power assay...

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...

Present study shows the Rationale behind the synthesis of chelating agents and their thermodynamic stability along with kinetic inertness of metal complex in vivo is the prerequisites for the successful application of bifunctional chelating agentconjugate. Macrocyclic bifunctional chelating agents (BFCs) with their established stabilizing properties are in the forefront for radio-immuno applica...

Water extract from Pinus densiflora (WPD) was investigated for its antioxidant activity and its ability to provide protection from DNA damage. A series of antioxidant assays, including a 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical-scavenging assay, a reducing power assay, a metal-chelating assay, a superoxide radical scavenging assay, and a nitrite scavenging ability, as well as a DNA dam...

Purpose: To evaluate protein hydrolysates and membrane ultrafiltration fractions of blue-spotted stingray for metal chelating and radical scavenging activities, as well as protection against oxidative protein damage. Methods: Stingray protein isolates were hydrolysed with alcalase, papain and trypsin for 3 h. Alcalase hydrolysate was fractionated by membrane ultrafiltration to yield < 3, 3 10 a...

Rice blast caused by Pyricularia oryzae, which is a major threat to food security worldwide, markedly decreases the yield of rice. Some rhizobacteria called 'plant growth-promoting rhizobacteria' inhibit plant pathogens and improve growth secreting iron-chelating siderophores. The decreased availability iron adversely affects survival pathogens, especially fungal in rhizosphere. This study aime...
