Objective: Allium elburzense is an endemic plant of the family Amaryllidaceae that grows wild in northern Iran with some nutritional and medicinal applications. The present study was aimed to investigate the fibrinolytic and antioxidant effects of A. elburzense bulb extracts. Materials and Methods: Hydroalcoholic, aqueous, chloroformic and butanolic extracts were evaluated in this research. In ...

general toxicity, antiproliferative, antibacterial and antioxidant activities of caulerpa peltata j.v.lamouroux (caulerpaceae) collected from oman sea were investigated. dried, ground alga was soxhlet-extracted with hexane, dichloromethane and methanol successively. the methanol extract was subjected to vacuum liquid chromatography (vlc) fractionation on silica gel using a step gradient of diff...

Methods: The study was initiated by preliminary phytochemical screening to detect the presence of carbohydrates, flavonoids, alkaloids, saponins and tannins. Quantitative analysis of phenolic and flavonoids was carried out by Folins Ciocalteau reagent method. In vitro antioxidant activities were performed by DPPH free radical scavenging assay, Reducing power assay, Total antioxidant assay and T...

Total phenolic content (TPC) and total antioxidant capacity (TAC) of four onion varieties (red, white, yellow and sweet) and shallot from selected locations (Washington, Idaho, Oregon, Texas and Georgia) were determi...

Background: Cornus sanguinea L subsp australis (C.A. Mey.) Jáv. (Cornaceae) is a native species in north and northwest of Iran. It is locally named Siah-al. The genus Cornus is rich source of anthocyanins. Objective: In this study the antioxidant activity, total phenol and total anthocyanin contents of different extracts of C. sanguinea L subsp australis. were investigated for the first time. ...

The aim of this study was to investigate the antioxidant activity of orange (Citrus auranthium) flesh (OF) and peel (OP) extracted with acetone, ethanol, and methanol. Antioxidant potential was examined by measuring total phenolic content (TPC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity (RSA), total radical-trapping anti-oxidant potential (TRAP), oxygen radical absorbance...

Aim:The present study aimed to assess the in vitro antioxidant and anticancer properties of Drosera peltata J.E.Sm. Methods:Antioxidant capacity of the extracts were tested on hydroxyl, DPPH, super oxide, nitric oxide and ABTS radicals; of ferrous ion chelating ability and by reducing power assay.Ascorbic acid was used as the standard antioxidant for the above all assay methods. Dalton’s Asciti...
