Evaluation of antioxidant activity of Ruta graveolens L. extract on inhibition of lipid peroxidation and DPPH radicals and the effects of some external factors on plant extract's potency.
The antioxidant properties of Ruta graveolens L. were evaluated by two different methods; free radical scavenging using DPPH and inhibition of lipid peroxidation by the ferric thiocyanate method. The IC50 value of the methanol extract in DPPH inhibition was 200.5 μg/mL which was acceptable in comparison with BHT (41.8 μg/mL). In thiocyanate method, the plant extract demonstr...

متن کاملScreening of various botanical extracts for antioxidant activity using DPPH free radical method.
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...
متن کاملAntioxidant, antiglycation and inhibitory potential of Saraca ashoka flowers against the enzymes linked to type 2 diabetes and LDL oxidation.
OBJECTIVE The present study investigated the antioxidant, antiglycation and inhibitory potential of flavonoid fraction of Saraca ashoka flowers (SAF) against alpha-glucosidase and alpha-amylase (the enzymes linked to type 2 diabetes) and LDL oxidation. MATERIALS AND METHODS Antioxidant capacity of SAF was evaluated by estimating total antioxidant activity (TAA) and its protective effects agai...
متن کاملFlavonoids from Machilus japonica Stems and Their Inhibitory Effects on LDL Oxidation
Stems of Machilus japonica were extracted with 80% aqueous methanol (MeOH) and the concentrated extract was successively extracted with ethyl acetate (EtOAc), normal butanol (n-BuOH), and water. Six flavonoids were isolated from the EtOAc fraction: (+)-taxifolin, afzelin, (-)-epicatechin, 5,3'-di-O-methyl-(-)-epicatechin, 5,7,3'-tri-O-methyl-(-)-epicatechin, and 5,7-di-O-methyl-3',4'-methylened...
