Picea smithiana is one of the plants belongs to family pinaceae that has not been explored scientifically from pharmaceutical point of view. The present study targeted to explore the antioxidant potential of Picea smithiana growing in Bhadewah region (Shoj dhar) at the altitude of 11000 feats of Jammu and Kashmir, India. Three types of extracts were prepared from leaf and Bark part of the plant...

Orphanides A., Goulas V., Gekas V. (2013): Effect of drying method on the phenolic content and antioxidant capacity of spearmint. Czech J. Food Sci., 31: 509–513. The changes in total phenolics, hydroxycinammic acid derivatives, and antioxidant properties of spearmint after five drying treatments (convection oven drying, freeze-drying, microwave drying, and air drying with the sun exposure and ...

BACKGROUND Mad1 and Mad2 are constituents of the spindle-assembly checkpoint, a device coupling the loss of sister-chromatid cohesion at anaphase to the completion of microtubule attachment of the sister chromatids at metaphase. Fluorescence recovery after photobleaching (FRAP) revealed that the interaction of cytosolic Mad2 with kinetochores is highly dynamic, suggesting a mechanism of catalyt...

the antioxidant and cytotoxic properties of four major parts of methanolic extracts of tephrosia purpurea including leaves, root, stem and seed were investigated and compared. in vitro antioxidant activity of t. purpurea extracts was evaluated using 1,1-diphenyl-2-picrylhydrazyl (dpph), ferric reducing antioxidant power (frap), reducing power assay and antihemolytic assay. in vitro cytotoxic ef...

Vitellaria paraodoxa (shea tree) is the source of shea seed from which well-known butter derived. The methanol extract was evaluated for its anti-inflammatory and antioxidant activities using diclofenac sodium ascorbic acid as standard respectively in vitro methods. activity determined by inhibition protein denaturation bovine serum albumin (BSA) erythrocyte membrane stabilization human red blo...

The objective of this study was to evaluate total phenolic content and antioxidant activity of leaf and different parts of fruit (hull, shell, and kernel) of Bene in Ilam province. Total phenolic content was determined with the FolinCiocalteu Reagent (FCR); antioxidant activity of methanolic extracts were examined by DPPH (2,2diphenyl1picrylhydrazyl), FRAP (ferric reducing antioxidant power) an...

The natural product rapamycin has been used to provide temporal and quantitative control of gene expression in animals through its ability to interact with two proteins simultaneously. A shortcoming of this approach is that rapamycin is an inhibitor of cell proliferation, the result of binding to FKBP12-rapamycin-associated protein (FRAP). To overcome this limitation, nontoxic derivatives of ra...

The present study was designed to evaluate relative contribution of different polyphenols (total phenolics, flavonoids, flavonols) and their antioxidants activities in aqueous extracts of different parts of some plants; Argemone mexicana, Datura metel, Calotropis procera, Thevetia peruviana, and Cannabis sativa. The antioxidants (total phenolics, flavonoids, flavones) were determined by chemica...

antioxidant activities protect the cell against oxidative agents that are constant metabolic by-products. the aim of this study was to investigate the relationship between harvesting time of thymus transcaspicus and its antioxidant activities. the plant samples were harvested 5 times in different growth phases from 17 april to 22 july 2008, and its antioxidant activity was studied using the fer...

Aqueous extracts of 30 plants were investigated for their antioxidant properties using DPPH and ABTS radical scavenging capacity assay, oxygen radical absorbance capacity (ORAC) assay, superoxide dismutase (SOD) assay, and ferric reducing antioxidant potential (FRAP) assay. Total phenolic content was also determined by the Folin-Ciocalteu method. Antioxidant properties and total phenolic conten...
