potential antioxidant activity using the quantitative2,2-diphenyl-1-picrylhydrazyl (DPPH)-free radical scavenging method and theircytotoxic effects were evaluated in the MTT assay using human ...
Isolation and characterization of the compounds responsible for the antimutagenic activity of Combretum microphyllum (Combretaceae) leaf extracts
Ames test using Salmonella typhimurium TA98, TA100 and TA102. The antioxidant activity of the three compounds were determined by the quantitative 2,2-diphenyl-1-picrylhydrazyl (DPPH)-free radical ...
The correlation between antimutagenic activity and total phenolic content of extracts of 31 plant species with high antioxidant activity.
most promising extracts were selected for further assays. The quantitative antioxidant activity was determined using DPPH free radical scavenging spectrophotometric assay. Total phenolic contents were ...

Factors Influencing Benzene Formation from the Decarboxylation of Benzoate in Liquid Model Systems
Practice Reduction study System Type Yield Abstract: Benzene may occur in foods due to the oxidative decarboxylation of benzoate in the presence of hydroxyl radicals. This study investigated factors ...
A simple and fast HPLC method to determine lycopene in foods
and nutrition. They are also recognised as strong antioxidants due to their ability to trap singlet oxygen and eliminate the peroxyl radical. The availability of reliable information on lycopene content ...
The occurrence and formation of benzene in foodstuffs
At low pH, hydroxyl radicals are supposed to be the key intermediate for this oxidative mechanism.This paper studied the occurrence and formation of benzene in foodstuffs. Therefore, a sensitive ...
Perinatal mortality and other severe adverse pregnancy outcomes associated with treatment of cervical intraepithelial neoplasia: meta-analysis.
treatment with cryotherapy or laser were not associated with a significantly increased risk of serious adverse pregnancy outcomes. Ablation by radical diathermy was associated with a significantly higher ...
