Various methods employed in evaluating antioxidant activities of various samples gives varying results depending on the specificity of the free radical or oxidant used as a reactant. This study investigated the antioxidant /radical scavenging properties of the methanolic extract of Vernonia amygdalina (MEVA) leaves and studied the relationship between the assay methods. Antioxidant capacity of ...

the aim of present study was to investigate and compare antioxidant properties of green tea and rosemary extracts and determine the effect of their combination on the antioxidant properties. results of total phenols, dpph free radical scavenging assay, total antioxidant capacity, reducing power and their addition into soybean oil, showed that the green tea extract was significantly (p<0.05) mor...

In this investigation, the In-vitro antioxidant Activity of extracts leaves Ougeinia oojeinensis was evaluated. The activity in vitro measured by means DPPH, Reducing power and hydroxyl radical scavenging activity. DPPH ethyl acetate extract exhibited percent inhibition 66.774% its IC50 value found to be 43.503μg/ml. methanol 76.267% 25.722μg/ml. Ascorbic acid used as a reference compound which...

To investigate the ulcer protective and antisecretory properties of the methanolic extract of Butea monosperma (BM) bark with relation to antioxidant studies. The study was done on male albino rats. &nbsp; Gastric ulcers were induced by Aspirin, Alcohol and Pylorous ligation. Lansoprazole was used as the standard drug for comparison. The free radical scavenging potential of the bark of BM ...

Mallotus philippinensis is an important source of molecules with strong antioxidant activity widely used medicinal plant. Previous studies have highlighted their anticestodal, antibacterial, wound healing activities, and so forth. So, present investigation was designed to evaluate the total antioxidant activity and radical scavenging effect of 50% ethanol fruit glandular hair extract (MPE) and ...

the study was aimed at evaluating the antioxidant activity of hydroalcoholic solution extracts of urtica dioica l. (ud), malva neglecta wallr. (mn) plants and their mixture. in this study, flower (udf), root (udr), seed (uds) and leaf (udl) parts of ud and flower (mnf) and leaf (mnl) parts of mn were used. the antioxidant properties of hydroalcoholic extracts and their mixture were evaluated us...

A detailed study has been performed on the antioxidant activity of the acetone and methanol extracts of the stem bark of the plant, Shorea roxburghii. The total phenolic content and antioxidant activity of the extracts were determined by DPPH, radical scavenging, ferric ion reducing power, hydroxyl radical, ABTS(.) radical scavenging and hydrogen peroxide scavenging activities. Reducing efficie...

Indian Ber contain good source of ascorbic acid and total phenolics. Despite being rich in antioxidants it is an underutilized fruit. Effect of processing on antioxidant activity of ber fruit was studied. Antioxidant activity of ber fruit was evaluated by different methods viz. DPPH radical activity, reducing power assay, superoxide anion radical activity, TBARS, total phenolic content and tota...

The present study was carried out to evaluate the antimicrobial and antioxidant activities of methanol extract of Careya arborea (MECA) stem barks (Myrtaceae) in various in-vitro systems. Antimicrobial activities of MECA were carried out using disc diffusion methods with Gram positive and Gram negative bacteria and some fungal species. MECA showed broad-spectrum antimicrobial activity against a...

in this study, we have examined the antioxidant activity and total phenolic content of different extracts (including water, methanol, water : methanol and acetone) of nerium oleander l. grown in the north of iran by employing various in-vitro assay, i.e. dpph free radical scavenging, reducing power and total antioxidant capacity through the mo (vi) reduction. the extracts showed different level...
