The antioxidant effects of meat fractions from chicken breast and beef loin were compared. Five meat fractions - homogenate (H), precipitate (P), supernatant (S), high-molecular-weight (HMW) and low-molecular-weight (LMW) fractions - were prepared from chicken breast or beef loin. Each of the fractions were added to a phospholipid liposome model system containing catalysts (metmyoglobin, ferrou...

Background: A new type of treatment is still needed for sporadic Alzheimer disease. The ion chelating agent (such as M30 and HLA-20) and other kinds of ion chelating agent possess brain tissue permeability. At present, the study has confirmed that ion chelating agent possesses a certain neuroprotective effect on neural degenerative disease. The objective of this study is to explore the related ...

The involvement of metal in oxidation and coupled phosphorylation by cell-free preparations of Mycobacterium phlei was examined. The oxidation of succinate was inhibited by metal-chelating agents, but with /3-hydroxybutyrate, chelating agents exhibited an uncoupling effect. The site of inhibition was found to be between the flavoprotein and the cytochrome b regions of the electron transport cha...

The antioxidant and antimicrobial properties of hot water extract (WE) obtained from Dictyophora indusiata were investigated. The free radical scavenging ability of WE on DPPH• was 97.35% at 2 mg/ml concentration. The reducing power of WE was moderate (1.22 at 2 mg/ml). Similarly, the WE displayed average scavenging effect on hydroxyl radical (52.28% at 2 mg/ml) and superoxide anion scavenging ...

Aconitum kusnezoffii Reichb., one of the earliest recorded toxic species of genus Aconitum, has been used as traditional Chinese medicine and medicinal diet over the last 2500 years to treat heart failure congestion, neuralgia, rheumatism and gout, etc. In the present paper, four water-soluble polysaccharide fractions isolated from the tubers of A. kusnezoffii Reichb. were studied the antioxida...

Alternanthera bettzickiana (Regel) Nicholson (Family: Amaranthaceae) is an erect herb and an ornamental pot plant, claimed to be useful in purifying and nourishing blood, in addition to the acclaimed soft laxative, galactagogue, antipyretic and wound healing characteristics. The tender leaves and shoots are commonly consumed like vegetable or spinach and in soups, either cooked alone or mixed w...

Soluble and bound phenolic compounds were extracted from different varieties of millet types namely, finger millet, foxtail, and proso millet cultivated at dry and intermediate climatic zones in Sri Lanka. The extracts were examined for their total phenolic content (TPC), total flavonoid content (TFC), and proanthocyanidin content (PC). The antioxidant activities were meassured by reducing powe...

Commelinaceae is a family of herbaceous flowering plants with many species used in ethnobotany, particularly in South America. However, thus far reports of their bioactivity are few and far between. The primary aim of this study was to quantify the antioxidant and antibacterial activity of five Commelinaceae methanolic leaf extracts. The antioxidant content was evaluated by the total phenolic c...

The effects of tea catechins, including (–)-epicatechin (EC), (–)-epigallocatechin (EGC), (–)-epicatechingallate (ECg) or (–)-epigallocatechingallate (EGCg) on the lipid peroxidation induced by either ferrous (Fe), copper (Cu) or vanadium (V ) ions were examined in normal and α-linolenic acid-loaded (LNA-loaded) cultured rat hepatocytes. The order of antioxidative activity was almost similar an...

Alternanthera bettzickiana (Regel) Nicolson is an erect herb and an ornamental pot plant, which is recorded to be useful in purifying and nourishing blood. It is also claimed to be a soft laxative, a galactagogue and an antipyretic in addition to its wound healing property. The leaves are reported to be used like spinach and in soups. The lipophilic acetone extract of the fresh flowers exhibite...
