the aim of the study was to evaluate the antioxidant and free radical scavenging properties and to determine the phenolic content of the ethanol extract from five mentha species [m. longifolia (l.) huds., m. piperita l., m. pulegium l., m. rotundifolia (l.) huds., and m. spicata l.]. the antioxidant activities of the extracts were investigated with two different methods, 2,2’-diphenyl-1-picrylh...

Safety and beneficence of farm animal nutrition plays a great role in their healthy life which in turn have impact on human nutrition via diary or meat products. Assessing safety and beneficence of Vicia varibilis Freyn and Sint. Which is chosen intrinsically by domesticated animals of Kohgiluyehand Boyerahmad Iranis the aim of the present work. Our results not only show no cytotoxic activity i...

The aim of the study was to evaluate the antioxidant and free radical scavenging properties and to determine the phenolic content of the ethanol extract from five Mentha species [M. longifolia (L.) Huds., M. piperita L., M. pulegium L., M. rotundifolia (L.) Huds., and M. spicata L.]. The antioxidant activities of the extracts were investigated with two different methods, 2,2’-diphenyl-1-picrylh...

Moringa oleifera leaves extracted with methanol and dichloromethane were screened for antioxidant activity. The in vitro cancer antiproliferative and chemopreventive properties were also investigated. Radical scavenging assays with 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2 ́-azino-bis 3ethylbenzothiazoline-6-sulfonic acid (ABTS) were used to determine the antioxidant activity. The antiprolif...

In the present study, antioxidant potential of the methanol extract of the leaves of Mimusops elengi Linn. was evaluated by using 1, 1-diphenyl-2-picrylhydrazyl (DPPH) scavenging assay, reducing power and total antioxidant capacity. The extract showed significant activities in all antioxidant assays compared to the reference antioxidant ascorbic acid in a dose dependent manner. In DPPH scavengi...

New sulfonamide and amide derivatives containing coumarin moieties; oxo-2H-chromen-sulfamoylphenylacetamides and oxo-2H-chromen-arylacetamides were synthesized starting from diverse 2-chloroacetamide derivatives and a wide range of coumarins. The structures of compounds were elucidated by IR and NMR spectra and also analytical elemental analysis. In the next step, the above mentioned compounds ...

The antidiabetic and antioxidant potential of ethanolic extract of Cassia nemophila pod (EECNP) was evaluated by three in vitro assays, including yeast glucose uptake assay, glucose adsorption assay, and DPPH radical scavenging activity. The result revealed that the extracts have enhanced the uptake of glucose through the plasma membrane of yeast cells. A linear increase in glucose uptake by ye...

BACKGROUND Quercetin is one of the most potent antioxidants showing anti-inflammatory, antiproliferative and antitumoral effects; however its short half-life in buffered solution (e.g. body fluids) has so far hampered its introduction into clinical practice. AIM To overcome this inconvenience, quercetin was covalently conjugated into a polymethacrylic acid backbone and the conjugate was teste...

To investigate the biological activities of anthocyanins, which are induced by cadmium in A. imbricata, the antioxidant properties of anthocyanins were investigated using various antioxidant assays, namely 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, 2,2'-azinobis-(3-ethylbenzthiazoline-6sulfonic acid) (ABTS) radical scavenging activity, reducing power, and β-carotene bleac...

The aim of this study was to evaluate complexes of L-ascorbyl palmitate (ASCP) and urea (UR). This evaluation involved differential scanning calorimetry (DSC), powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), near-infrared spectroscopy (NIR), a solubility test, a 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging test, and a mushroom tyrosinase inhibition assay. Physico...
