Ethanolic extract of leaves of Elaeocarpus ganitrus was analyzed for their total antioxidant capacity, reducing power, metal chelating, ABTS+ (2, 2-azinobis-(3-ethylbenzothiazoline-6-sulphonate) radical scavenging and hydroxyl radical scavenging activities. The extract at 500 ?g/ml showed maximum Iron chelating activity (76.70%) followed by the scavenging of the ABTS+ radical (55.77%) at the sa...

a pot experiment was conducted to evaluate the extract biochemical variations among 25 spearmint population. the experiment was a randomized complete design (rcd) with 25 treatments (population) and three replications. for this purpose, three rhizomes with 5 cm length were selected and planted in each pot. all pots were kept out side. the plant samples of all treatments were harvested at full f...

abstract in this study, the physicochemical quality and antioxidant activities of fruits peel from 6 citrus varieties which commonly consumed in the north of iran were determined. some parameters were measurement such fruit size, peel thickness, residue percentage, peel color indices, total phenolics, total flavonoid, total anthocyanins, total carotenoids, total chlorophyll, ascorbic acid conte...

the essential oil from the aerial parts ofjurinea leptoloba dc., collected from shiraz (south of iran), was investigated for total phenolic content (tpc), antioxidant and cytotoxic effects. tpc of j. leptoloba oil was determined to be 16.53 ± 5.69 μg gallic acid equivalent/mg sample (μg gae/mg oil) using the folin-ciocalteau assay. the ferric reducing power of the oil was determined 0.117 ± 0.0...

objective: antioxidants are considered as the main factors in the inhibition of unwanted oxidation reactions. materials and methods: in this research the antioxidant potential of the fresh fruits of 4 cultivars (a to d) of malus domestica (m. domestica) cultivated in the kashan, qamsar area was evaluated. the antioxidant activity of the samples were evaluated using two complementary antioxidant...
