Antioxidants are compounds that able to stabilize free radicals in the body. Free highly reactive molecules because they have unpaired electrons so can interact with of body's cells. One plants has properties as an antioxidant for star fruit (Averrhoa bilimbi L.) Star is one species genus Averrhoa. The purpose this study was find out what active contained ethanol extract 70% and determine activ...

Siamese oranges (Citrus nobilis) are one of Bali's most widely developed citrus fruits, especially in the Kintamani area. contain many secondary metabolite compounds as a source natural antioxidants. In this study, plants were obtained through extraction method. addition to method, selecting type solvent is main factors affecting results. Polar solvents tend produce higher antioxidant activity,...

Abstract Salicornia europaea L. is a common halophytic plant species distributed in many saline soils and habitats, including margins of many wetlands. Salicornia europaea grows around Mighan Wetland, a natural desert ecosystem in central Iran with fluctuating water levels due to constant heat and severe wind throughout the year. Although, aspects of biology and ecology of halophytes growi...

Extracts prepared by culturing ten filamentous fungi from Aspergillus and Eurotium species isolated from dried bonito (katsuobushi) were examined for 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging capacity. The extracts prepared by culturing E. herbariorum NE-1 and NE-4, which are used in the molding process for the manufacture of karebushi (a kind of katsuobushi), were shown to have h...

The development of new antioxidants with enhanced activity constitutes a very active research field as it can contribute to the improvement of human health. Although the antioxidant activity occurs through different mechanisms, usually most of the antioxidant molecules present a unique active center which is able to react following a specific way. To overcome this weakness and in the belief tha...

We are glad to share the editorial summary of Special Issue on "Biological Activity Evaluation Process Natural Antioxidants," edited by Chang-Wei Hsieh and Jer-An Lin National Chung Hsing University [...]

Antioxidants are substances that fight against ROS (reactive oxygen species) and protect the cells from their damaging effects. Production of ROS during cellular metabolism is balanced by their removal by antioxidants. Any condition leading to increased levels of ROS results in oxidative stress, which promotes a large number of human diseases, including cancer. Therefore antioxidants may be reg...
