The objective of the study was to investigate the anti-oxidant and anti-inflammatory effect of aqueous extract of Ocimum sanctum leaf. The antioxidant and anti-inflammatory activities were evaluated using in vitro Ferric reducing power, Free radical scavenging activity by DPPH method, hydroxyl radical scavenging activity, Nitric oxide radical scavenging activity, Hyaluronidase inhibition assay....

Six different extracts of Canarium patentinervium Miq. (Burseraceae) leaves and barks were screened for their phytochemical composition, and antimicrobial and free radical scavenging activities. Among the different extracts tested, the ethanol extract of leaves showed significant antimicrobial and radical scavenging activities. The most susceptible micro-organisms were found to be Gram-positive...

the crude methanolic extract of the seeds of celastrus paniculatus along with its organic soluble fractions were tested for their possible antioxidant and anti-alzheirmer (ad) activity. the extracts showed prominent dpph free radical scavenging activity, inhibiting activity of authentic peroxynitrite (onoo-) and inhibition of total reactive oxygen species (ros) generation. in dpph radical scave...

[1] The balance of processes that control elemental distributions in the modern oceans is important in understanding both their internal recycling and the rate and nature of their eventual output to sediment. Here we seek to evaluate the likely controls on the vertical profiles of Cu and Zn. Though the concentrations of both Cu and Zn increase with depth, Cu increases in a more linear fashion t...

To examine the antioxidant capacity of normal human airway secretions and to characterize its molecular components, tracheal lavages were obtained from eight patients intubated for elective surgery and free of lung disease. These samples (20 microl, approximately 6.8 microg of protein) scavenged 0.57 +/- 0.09 nmol of added 0.96 nmol hydrogen peroxide (H2O2) within 10 minutes at room temperature...

Plants are rich in a variety of chemical compounds. Many are secondary metabolites including aromatic substances most of them are phenols or their oxygen substituted derivatives. Medicinal plants are rich in antioxidant constituents such as phenols, tocopherols, ascorbic acid, carotenoids, and flavonoids etc. They are found to acquire free radical scavenging activity and used worldwide for the ...

Despite strawberry tree (Arbutus unedo L.) leaves had a long use in traditional medicine due to its antiseptic, diuretic, astringent and depurative properties, the potential of their antioxidant activity are still lacking. Our study goals to assess the antioxidant and free radical scavenging potential of water, ethanol, methanol and diethyl ether extracts of A. unedo leaves. Total phenols conte...

In this present study our aim was to evaluate In vitro antioxidant and free radical scavenging potential of methanolic extracts of Bauhinia variegata Linn. Different parts of Bauhinia variegata like leaves, bark and flowers have free radical scavenging activity by hydroxyl radical scavenging method. All extracts have different level of antioxidant activity. Methanol extracts was found to be goo...

In the present study, the antioxidant activity of the polysaccharides from aloe vera (Aloe barbadensis Miller) gel was evaluated, in vitro by five established methods, 1,1-diphenyl-2-picrylhydrazyl (DPPH(-)) radical scavenging, nitric oxide (NO) scavenging, hydrogen peroxide scavenging, superoxide radical (O(-2)) scavenging and reducing power assay, and in vivo against doxorubicin (DOX)-induced...

The antioxidative capacity of seven different porcine tissue hydrolysates (colon, appendix, rectum, pancreas, heart, liver, and lung) were tested by four different assays, including iron chelation, 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging, 2,2-Diphenyl-1-(2,4,6-trinitrophenyl) hydrazyl (DPPH) radical scavenging, and inhibition of lipid oxidation. All hyd...
