Free radical-scavenging activities of Crataegus monogyna extracts

In vitro screening of Crataegus succulenta extracts for free radical scavenging and 15-lipoxygenase inhibitory activities.

UNLABELLED Crataegus succulenta Schrad. ex Link is widely spread in North America. A literature survey revealed no studies on the chemical composition and biological effects of this species. AIM The aim of the present study was to investigate the phenolic content, free radical scavenging and 15-lipoxygenase inhibitory effects of Crataegus succulenta leaf and flower extracts. MATERIAL AND ME...

Free Radical Scavenging Activities of Zizyphus mauritiana

In the present study, antioxidant activities of the two varieties of fruits of Zizyphus mauritiana (Boroi) were investigated. Ethanolic extracts of fruits powder were characterized by the method described by Hatano et al. [1] in which stable 1, 1-diphenyl-2-picrylhydrazyl (DPPH) free radical solution were used. In the present investigation, it is found that all of the fruit extracts have remark...

Phytochemical Characteristics, Free Radical Scavenging Activities, and Neuroprotection of Five Medicinal Plant Extracts

The objective of this study was to determine phytochemical characteristics, chemiluminescence antioxidant capacities, and neuroprotective effects on PC12 cells for methanol extracts of Spatholobus suberectus, Uncaria rhynchophylla, Alpinia officinarum, Drynaria fortunei, and Crataegus pinnatifida. The C. pinnatifida extract (CPE) afforded the greatest yield and total phenolic content. The S. su...

Antioxidant and Free Radical Scavenging Activities of Ervatamia coronaria Stapf. Leaves

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...
