Antioxidant and nitrite-scavenging capacities of phenolic compounds from sugarcane (Saccharum officinarum L.) tops.
Sugarcane tops were extracted with 50% ethanol and fractionated by petroleum ether, ethyl acetate (EtOAc), and n-butyl alcohol successively. Eight phenolic compounds in EtOAc extracts were purified through silica gel and Sephadex LH-20 column chromatographies, and then identified by nuclear magnetic resonance and electrospray ionization mass spectra. The results showed that eight phenolic compo...
متن کاملSuperoxide-dependent and -independent nitrite formation from hydroxylamine: inhibition by plant extracts.
Reactive oxygen species such as OH, peroxynitrite and the non-radical, hypochlorous acid, play outstanding roles in many disease. The formation of OH (Fenton)-type radicals is catalyzed by enzymes such as xanthine oxidase (XOD) via one-electron reduction of molecular oxygen producing superoxide radical anions (O2). Subsequent transfer of one electron to hydrogen peroxide by Fe2+ or Cu+ -ions yi...
متن کاملFlavonoid 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...

متن کاملFree 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...
