In aerobic organisms, protection from oxidative damage involves the combined action of enzymatic and nonproteinaceous cellular factors that collectively remove harmful reactive oxygen species. One class of nonproteinaceous antioxidants includes small molecule complexes of manganese (Mn) that can scavenge superoxide anion radicals and provide a backup for superoxide dismutase enzymes. Such Mn an...

The objective of the study was to assess the antioxidant potential of defatted foxtail millet protein hydrolysates (DFMPH). Gel filtration (Sephadex G-25) chromatography was used to fractionate DFMPH. The amino acid composition, ABTS, DPPH, inhibition of linoleic acid autoxidation, metal-chelating free radical scavenging ability, and reducing power were tested to determine their antioxidant pot...

Abstract In traditional beekeeping, the two most important methods for extracting honey are centrifugation and honeycomb-pressing. this study, physicochemical composition of samples extracted using distinct procedures was compared, as well impact antioxidant capacity nutritional potency on lifespan learning memory worker bees. Honey were collected from ten colonies Apis cerana: five via Our res...

This study was designed to examine the in vitro antioxidant activities of the essential oil and methanol extracts of rhizoma Alpinia officinarum (small galanga) from China. The essential oil was analyzed by gas chromatography/ mass spectrometry (GC/MS) and 46 constituents were identified. Methanol extract from rhizoma A. officinarum was fractionated by chromatography of silica gel using ethyl a...

The leaves of Cassia tora (local name – puvad) are usually consumed as food ingredient in traditional recepies by local people of Haryana. In the present study, the antioxidant potency of sequential organic (petroleum ether, benzene, chloroform, methanol) and aqueous leaf extracts of Cassia tora plant was investigated by using various established in vitro systems such as nitric oxide scavenging...

The present investigation is design to determine the chemical composition of the essential oil of Eucalyptus camaldulensis grown in Egypt and to study its antioxidant and cytotoxic effects on different cancer and normal cell lines. The analysis of E. camaldulensis oil using GC/MS resulted in the identification of 43 compounds. The current results indicated that the essential oil has weak radica...

BACKGROUND Medicinal and aromatic plants play a significant role in drug discovery and development process. Flavonoids, revealing a wide spectrum of biological activities, extensively found in plants are important secondary metabolites. MATERIALS AND METHODS Aerial parts of Cyclotrichium origanifolium were collected, dried, and boiled in water then extracted with hexane, ethyl acetate, and n-...

Gastrointestinal (GI) mimic and organic solvent extracts of whole soybean powder (WSP), soy protein concentrate (SPC), and soy protein isolate (SPI) as well as soy isoflavone concentrate (SIC) were analyzed for total phenols; quinone reductase (QR) induction in hepa1c1c7 cells; antioxidant scavenging of DPPH, HOCl, ONOO(-), and O(2) (-.); and total antioxidant capacity via FRAP and ORAC assays....
