This study evaluated the efficacy of various organic solvents (80% acetone, 80% ethanol, 80% methanol) and distilled water for extracting antioxidant phenolic compounds from turmeric, curry leaf, torch ginger and lemon grass extracts. They were analyzed regarding the total phenol and flavonoid contents, antioxidant activity and concentration of some phenolic compounds. Antioxidant activity was ...

Available synthetic antioxidants have been reported to mutagenic and toxic effects. On the other hand, natural show their superiority as they are not or less toxic. Passiflora foetida has potential an antioxidant, but investigation of antioxidant activity P. chromatography column fraction reported. This studied aims investigate chromatographic fractions leaves. An assay using DPPH FRAP methods....

BACKGROUND Seaweeds are taxonomically diverse benthic algae, which are rich in bioactive compounds. These compounds have a potential application in medicine. OBJECTIVES The aim of the study was to investigate the bioactive properties of three seaweed samples, Enteromorpha antenna, Enteromorpha linza and Gracilaria corticata were collected from the shoreline of Mahabalipuram, Tamilnadu. MATE...

OBJECTIVE To explore the hepatoprotective and anti-oxidant activities of the methanolic leaf extract of Bridelia micrantha (B. micrantha) on paracetamol induced liver damage in Wistar rats. METHODS Parameters were measured including alanine aminotransaminase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), bilirubin and total protein. The anti-oxidant effects were studied ...

Apples (Malus domestica Borkh.) have been identified as one of the main dietary sources of antioxidants, mainly phenolic compounds. These compounds vary in their composition and concentration, among cultivars and fruit tissues. In this research, the total phenolic content (Folin-Ciocalteau assay), antioxidant capacity (Ferric Reducing Antioxidant Power, FRAP assay) and mineral composition in th...

β-Carotene (BC) is the most abundant carotenoid in human diet, almost solely as(all-E)-isomer. Significant amounts of (Z)-isomers of BC are present in processed food as well as in mammalian tissues. Differences are described for the activity of various BC isomers in forming retinal and protecting against cancer and cardiovascular diseases. Eccentric cleavage of BC leads to degradation products ...

Many medicinal plants have been reported to exhibit protective effects against many physiological diseases as a result of their phytochemical components which are effective antioxidants. This study was aimed at comparing the phenolic and flavonoids contents, antioxidant cytotoxic activities methanol extract Jatropha curcas seeds leaves. The cytotoxicity level J. assessed using brine shrimp leth...

Abstract Cellulose and ulvan were extracted sequentially from the green seaweed Ulva lactuca used for development of edible films with natural antioxidant properties. The composite composed cellulose, polyvinyl alcohol, glycerol as plasticizer different concentrations. interaction between film components was described by FT-IR analysis, which confirmed formation hydrogen bonding interactions ce...

Fluorescence recovery after photobleaching (FRAP) is a widely used imaging technique for measuring protein dynamics in live cells that has provided many important biological insights. Although FRAP presumes that the conversion of a fluorophore from a bright to a dark state is irreversible, GFP as well as other genetically encoded fluorescent proteins now in common use can also exhibit a reversi...

The inhibitory effects of ethanol (80%) and aqueous extracts Helichrysum stoechas (L.) Moench H. subsp. barrelieri (Ten) Nyman on acetylcholinesterase (AChE) butyrylcholinesterase (BChE), two sister enzymes associated with pathogenesis Alzheimer's disease (AD), as well elastase collagenase, linked to inflammation skin aging, were investigated. Simultaneously, antioxidant activity the was assess...
