Free Radical Scavenging Activities of Extracts from Pomelo

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...

Free Radical Scavenging Activity and Total Phenolic Content of Methanolic Extracts from Male Inflorescence of Salix aegyptiaca Grown in Iran

This study was designed to examine the in vitro antioxidant activities and total phenolic contents of the methanolic extracts from male inflorescence of Salix aegyptiaca L. grown in Iran. The methanolic extract (ME) and its three fractions including water (WF), butanol (BF) and chloroform (CF) were prepared and then their antioxidant activities, as well as total phenolic contents, were evaluate...

Flavonoid Contents and Free Radical Scavenging Activity of Extracts from Leaves, Stems, Rachis and Roots of Dryopteris erythrosora

The present study was designed to explore the flavonoid contents and the radical scavenging activities of 50% ethanol extracts of leaves, stems, rachis and roots of Dryopteris erythrosora. The total flavonoid contents in various parts were determined as: stems > roots > rachis > leaves. All extracts from different parts of D. erythrosora showed strong bioactivities. The DPPH free radical scaven...
