Antioxidants are vital substances which possess the ability to protect the body from damage caused by free radical induced oxidative stress. A variety of free radical scavenging antioxidants exist within the body which many of them are derived from dietary sources like fruits, vegetables and teas. In this study the antioxidant activity and radical scavenging activity of methanolic extracts of s...

To quantify the major secondary metabolites and the antioxidant potential of methanolic extract of Indigofera trita. The methanolic whole plant extract of Indigofera trita (MIT) was analaysed by HPLC and GC to determine various Phytochemicals. Free radicals scavenging activity of extract by using DPPH, NO and Super oxide radicals generated in vitro. The Methanolic extract of I. trita was found ...

the antioxidant potential of crude methanol extract (ce) as well as chloroform (cf), ethyl acetate (ef) and n-butanol (nf) soluble fractions of enhydra fluctuans lour, which is widely used in indigenous system of medicine for different purposes, were studied. the antioxidant potential of extract/different fractions were evaluated using different in vitro antioxidant models. in addition, total a...

There are plenty of antioxidant substances present in plants parts such as fruits, vegetables, medicinal herbs and the free radical scavenging molecules present in them are in the form of Phenolic compounds (phenolic acids, flavonoids, quinones, coumarins, lignans, tannins), Nitrogen compounds (alkaloids, amines), Vitamins, Terpenoids (carotenoids) and some other endogenous metabolites. Therape...

BACKGROUND Callistemon citrinus (Curtis.) (Family- Myrtaceae) is a popular evergreen shrub in Bangladesh. In the present study, the leaves of this plant have been assessed comprehensively for free radical scavenging, thrombolytic and membrane stabilizing activities. METHODS The leaves were collected, powdered and extracted with methanol. The extract was then concentrated and successively frac...

Free radicals involved in a number of diseases due to the oxidative damage to DNA, lipids, and proteins and which can result in failure of cellular functions. Dried plant bulbs and leaves methanolic and ethanolic extracts were prepared. Total antioxidant activities of the methanolic extracts of Romulea ramiflora and Gagea fibrosa were determined using β-caroten-linoleic acid assay. Romulea-...

Trigonella foenum-graecum (TG) is one of the important medicinal plant which have antioxidant, antidiabetic, antilipidemic and antimicrobial properties. The main aim this study was to evaluate free radical scavenging properties, total phenolic, flavonoid content phytochemical screening foenum-graecum. antioxidant activities like 2,2-diphenylpicrylhydrazyl (DPPH), hydroxyl activity, hydrogen per...

free radicals involved in a number of diseases due to the oxidative damage to dna, lipids, and proteins and which can result in failure of cellular functions. dried plant bulbs and leaves methanolic and ethanolic extracts were prepared. total antioxidant activities of the methanolic extracts of romulea ramiflora and gagea fibrosa were determined using β-caroten-linoleic acid assay. romulea-bulb...

Aiming at the exploration of herbal use by society, crude extracts of the seeds of some commonly used medicinal plants (Vitis vinifera, Tamarindus indica and Glycin max) were screened for their free radical scavenging properties using ascorbic acid as standard antioxidant. Free radical scavenging activity was evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical. The overall antioxi...

Background: Ferula gummosa Boiss. is a medicinal and economical plant belonging to Apiaceae family. It is a native herb of Iran and is in serious danger of extinction. Objective: Gamma irradiation is an environmental stress and can consider as a new tool to change the content of secondary metabolites in medicinal plants. The effect of gamma irradiation on phenolic content and radical sc...
