Antioxidant activity of methanolic extract of Abutilon indicum leaves was investigated for its free radical scavenging activity by determining the nitric oxide and superoxide radical scavenging activity. Maximum scavenging of nitric oxide and superoxide radical found were 28.74 % and 49. 62 % respectively at 250 μg/ml concentration.

A free radical scavenging activity is an important property of natural dietary compounds, caffeine and caffeic acid compound widely present in many fruits, vegetables and coffee. The present study focused on determining the antioxidant activity of caffeine, caffeic acid and (caffeine + caffeic acid) through invitro antioxidant experiments. Invitro lipid peroxidtion, 1,1diphenyl-2-picryl-hydrazy...

The present study was carried out to evaluate the antioxidant and free radical scavenging activity of methanolic extract of Ervatamia coronaria leaves (Apocynaceae) in various systems. DPPH radical, superoxide anion radical, nitric oxide radical and hydroxyl radical scavenging assays were carried out to evaluate the antioxidant potential of the extract. The antioxidant activity of methanolic ex...

Antioxidant activity of chloroform extract of Aesculus indica leaves was investigated for its free radical scavenging activity by determining the nitric oxide and superoxide radical scavenging activity. Maximum scavenging of nitric oxide and superoxide radical found were 27.62% and 48.65% respectively at 250 μg/ml concentration.

INTRODUCTION Jasminum sambac is a sub erect shrub with young shoots of ovate or elliptic glabrous simple leaves, entire margin, and acute apex with opposite arrangement, grown as an ornamental shrub in gardens and cultivated throughout the tropical and subtropical parts of India (1). Leaves, roots and flowers are used as lactifuge. The whole plant is used as diuretic, emmengogue, antihelminthti...

Radical Scavenging capacity Abstract: In-vitro antioxidant activity of methanolic extract of Rhinacanthus nasutus leaves was determined by DPPH free radical scavenging assay and Reducing Power assays. Ascorbic acid was used as standard and positive control for both the analysis. All the analysis was made with the use of UV-Visible Spectrophotometer. The methanolic extract of Rhinacanthus nasutu...

Free radicals are atoms or molecules with unpaired electrons. Many diseases are caused by free radicals. Normally, free radical formation is controlled naturally by various beneficial compounds known as antioxidants. Several analytical methods have been used for qualitative and quantitative determination of antioxidants, and each has its own specificity. This project aimed to evaluate antioxida...

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...

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...
