methanolic extracts of five native species of salvia from the labiatae family were evaluated for antioxidant activity in low-erucic acid rapeseed oil using the schaal oven test at 60°c, with deterioration monitored by determination of peroxide value, conjugated diene content and p-anisidine value. the activity of the salvia extracts was compared with that of tbhq, ascorbyl palmitate, and extrac...

butyl-hydroxytoluene (bht) is one of the major synthetic antioxidants with a wide range usage. replacement of artificial antioxidants with natural antioxidants is highly considered. in this research, the antioxidant activity of juniperus excelsa was investigated by using reducing power, dpph radical scavenging and inhibition of lipid peroxidation. also, the amounts of phenolic and flavonoid com...

Grasses are natural homogenous group of plants and belong to the Gramineae family (Poaceae). The value of grasses to mankind has been recognized since the dawn of human civilization and culture of cereal grasses. In the present study, Leptochloa uniflora Hochst (Poaceae) was subjected to antioxidant and phytochemical profiles using UV-Vis, FTIR and HPTLC. Antioxidant assays were studied using D...

 Background: In recent years, plants natural products have gained considerable attention as natural preservers for use in different industries. Due to their free radical scavenging activities, phenolic compounds can prevent a wide range of diseases such as cancers and cardiovascular and neurodegenerative diseases. For a long time, different Ferulago species have been in use as medicina...

Oxidized low density lipoprotein (LDL) promotes atherogenesis. Although pharmacological antioxidants such as probucol inhibit both LDL oxidation and atherosclerosis in hyperlipidemic animals, the effects of natural antioxidants such as vitamin E are inconclusive. To further determine the effects of supplemental dietary antioxidants in vivo, we evaluated whether combined dietary antioxidants (0....

The root of Ophiopogon japonicus has been used as a traditional Chinese medicine and also a functional food ingredient for a long time in China. In the present study, 17 different homoisoflavonoid compounds were identified in the root extract of O. japonicus by HPLC–DAD and LCMS/MS analyses. The antioxidant activity of the of chloroform/methanol (1:1, v/v), methanol and 70% ethanol extracts, an...
