BACKGROUND Recent investigations have shown that the antioxidant properties of plants could be correlated with oxidative stress defense and different human diseases. In this respect flavonoids and other polyphenolic compounds have gained the greatest attention. The plant Cytisus scoparius contains the main constituent of flavone and flavonals. The present study was undertaken to evaluate the in...

The assessment of interactions between natural antioxidants and other food matrix components represents the main step in the investigation of total antioxidant properties, in terms of potential health benefits. The diversity of chemical structures of natural compounds, besides their possible interactions, as well as the biological role and different modes of action makes it difficult to assess ...

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...

Nowadays, consumers are demanding more natural foods, obliging the industry to include natural antioxidants in foods. Natural antioxidants have been used instead of synthetic antioxidants to retard lipid oxidation in foods to improve their quality and nutritional value. This review discusses some aspects of recent research on antioxidant activity of plant extracts and natural compounds to impro...

Two non colored and one colored rice varieties from Minahasa Regency, North Sulawesi, Indonesia were analyzed to determine the phytochemicals and antioxidant properties as natural antioxidant sources. Different brans of rice varieties divided into two groups: red rice and non colored (Superwin and Cigeulis) were macerated by ethanol (70%) and extracted with organic solvents (butanol, ethyl acet...

background: nowadays, there's a growing demand for the natural antioxidants due to the harmful effects of synthetic antioxidants. therefore, introduction of new natural antioxidants (especially those with plant origin) is very important. objective: the present study explores the chemical constitution and antioxidant activity of leaf extract of hyssopus officinalis l. and extract of aerial ...

Diabetes mellitus is a complex and progressive metabolic disease which is associated with multiple complications. Chronic hyperglycaemia is the defining characteristic of diabetes mellitus. Hyperglycaemia leads to generation of free radicals and induces oxidative stress, which has become the chief factor that leads to diabetic complications. This review supports the use of antioxidant vitamins ...

Anthocyanin is the natural pigment which can easily extract from plants such as blackberry, mulberry and Karanda. Karanda (Carissa carandas Linn.) had the fully ripe dark violet fruit contains the large amount of natural anthocyanin. The effect of extraction conditions on anthocyanin content, total phenolic content, and antioxidant activity in the extract was investigated. The extract with high...

Basella alba fruit with dark blue skin and deep red violet flesh is a potential source of natural colorant. This study was aimed to evaluate the total betacyanin content, total phenol and to analyse the antioxidant activity against DPPH radical, superoxide anions, hydroxyl radical, metal chelating, hydrogen peroxide, FRAP, ABTS and deoxyribose degradation in a dose dependend manner. Betacyanin ...
