Chickpea-chelating peptides were purified and analysed for their iron-chelating activity. These peptides were purified after affinity and gel filtration chromatography from a chickpea protein hydrolysate produced with pepsin and pancreatin. Iron-chelating activity was higher in purified peptide fractions than in the original hydrolysate. Histidine contents were positively correlated with the ir...

BACKGROUND The phytochemistry and bioactivity of wetland macrophytes are underexplored. Plants are known as the natural sources of phytochemical beneficial to health. OBJECTIVE The objective of this study is to analyze the phytochemical profiles and bioactivities of 10 extracts prepared from different plant parts of wetland macrophytes Hanguana malayana, Ludwigia adscendens and Monochoria has...

BACKGROUND Sarcandra glabra (Caoshanhu) is a traditional Chinese herbal medicine used for treating various oxidative-stressed diseases. The present work evaluated its protective effect on mesenchymal stem cells (MSCs) from oxidative stress and then discussed possible mechanisms underlying this observation. METHODS Ethanolic extract of S. glabra (ESG) was investigated by chemical methods for i...

Korean fir (Abies koreana Wilson) is traditionally used in folk medicine for its antibacterial, memory-enhancing, and anti-inflammatory properties. In this study, we evaluated the antioxidant skin-whitening effects of methanol ethanol extracts needles. The were tested their capacity using various assays, including radical scavenging (1,1-diphenyl-2-picrylhydrazyl, O2-, H2O2 NOž), SOD-like, ferr...

a chelating resin of polystyrene divinylbenzene resin functionalized by 1-(2-pyridylazo) 2- naphtol (psdvb-pan) has been synthesized and its sorption properties have been investigated for preconcentration and determination of cadmium at μg/l level by flame atomic absorption spectrometry. the procedure is based on the sorption of cd(ii) ions on a minicolumn of synthesized chelating resin. the...

Objective(s): Active species used in bio-chemical for synthesizing nanoparticles is poly phenolic compounds. The ability of flavonoids (e.g. quercetin) to dissolve in water is low and the production of metallic nanoparticles from them in the aqueous medium is hard. Previous studies recommend that quercetin was not capable of reducing Ag+ to Ag0. The current research aimed at synthesizing querce...

Solanum nigrum is a traditional medicinal plant renowned as cure for many diseases due to the presence of bioactive compounds. The complex refers group more than 30 closely related but morphologically distinct taxa. Five indigenous taxa this were investigated their potential by using methanolic extracts. efficacy each was different seven bacteria studied. On comparing MIC values, S. americanum ...

Purpose: The objectives of this study were to evaluate inhibition activities acetone, chloroform, ethanol and hot water extracts nutmeg (Myristica fragrans Houtt.) leaves against Salmonella enterica, Listeria monocytogenes, Shigella dysenteriae, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa Aspergillus niger and, assess the in vitro antioxidant discover active compound profile...

The animal assay of potential new iron-chelating agents is at present dependent on cumbersome and imprecise iron balance studies in hypertransfused rodents. We report the development of a radioisotope assay in intact rats based on the transient labeling by ferritin 59Fe of the main source of chelatable iron within hepatocytes. The isotope was maximally available to chelators during the first 6 ...
