Free Radical Scavenging Activity of Some Plants Available in Malaysia
The present study was carried out to determine the free radical scavenging properties of some plants, found in Malaysia. The air-dried leaves of each plant (20 g) were soaked in distilled water (1:20; w/v) for 72 h at room temperature. Collected supernatants were tested for free radical scavenging activity against the DPPH and superoxide anion radical scavenging assays. All extracts were found ...
متن کاملPhenylpropanoid Glycoside Analogues: Enzymatic Synthesis, Antioxidant Activity and Theoretical Study of Their Free Radical Scavenger Mechanism
Phenylpropanoid glycosides (PPGs) are natural compounds present in several medicinal plants that have high antioxidant power and diverse biological activities. Because of their low content in plants (less than 5% w/w), several chemical synthetic routes to produce PPGs have been developed, but their synthesis is a time consuming process and the achieved yields are often low. In this study, an al...
متن کاملFree Radical Activity and Plasma
The aim of this study is to evaluate the status of endogenous antioxidant defense system in H. pylori-infected endoscopically diagnosed chronic duodenal ulcer patients through the assessment of certain oxidative stress biomarkers. These biomarkers namely plasma malodialdehyde (MDA) and blood activities of superoxide dismutase (SOD) and glutathione peroxidase (GPx) are to be evaluated before and...
متن کاملTonal nitric oxide and health--a free radical and a scavenger of free radicals.
Basal/tonal nitric oxide (NO) production helps maintain particular microenvironments, i.e., vascular. Besides NO's function in controlling the activation state of various tissues such as immune cells, its presence appears to modulate other free radical levels, i.e., H2O2, in these same tissues and indeed these processes may be one and the same. Thus, by being a free radical, along with the abil...
متن کاملEdaravone, a Synthetic Free Radical Scavenger, Enhances Alteplase-Mediated Thrombolysis
The combination of alteplase, a recombinant tissue plasminogen activator, and edaravone, an antioxidant, reportedly enhances recanalization after acute ischemic stroke. We examined the influence of edaravone on the thrombolytic efficacy of alteplase by measuring thrombolysis using a newly developed microchip-based flow-chamber assay. Rat models of embolic cerebral ischemia were treated with eit...
