Free radical scavenging activities and inhibition of inflammatory enzymes of phenolics isolated from Tripodanthus acutifolius
(Elsevier Ireland, 2010-07)
Ethnopharmacological relevance: Leaf extracts from Tripodanthus acutifolius (Ruiz and Pavón) Van Tieghem have long been used in argentinean traditional medicine as anti-inflammatory, however, there is no scientific evidence ...
Free radical scavenging capacity and antioxidant activity of cochineal (Dactylopius coccus C.) extracts
(Elsevier, 2010-03)
Carminic acid (CA) is a natural red pigment produced by Dactylopius coccus C. insects. It is widely used in the food industry to replace synthetic colourants. Despite being known for a long time, its antioxidant properties ...
Effect of Dietary Astaxanthin on Free Radical Scavenging Capacity and Nitrite Stress Tolerance of Postlarvae Shrimp, Pleoticus muelleri
(American Chemical Society, 2014-11)
The aim of this study was to investigate the effect of astaxanthin feed supplementation and environmental nitrite stress in postlarvae of Pleoticus muelleri (15 ± 0.004 mg initial weight) under culture conditions. Diets ...
Correlation between radical scavenging capacity and carotenoid profile during Pleoticus muelleri larval development
(Int Science Services/Balaban Publishers, 2013-02)
The purpose of this study was to measure the concentration of carotenoids and properties which occur in tissues to neutralize free radicals during ontogeny of Pleoticus muelleri. The stages of nauplius, protozoea, mysis ...
Singlet oxygen quenching and radical scavenging capacities of structurally-related flavonoids present in Zuccagnia punctata Cav.
(Taylor & Francis Ltd, 2009-12)
The singlet oxygen (1O2) quenching and free radical (DPPH+, ABTS and O2 +) scavenging ability of three structurallyrelated flavonoids (7-hydroxyflavanone HF, 2´,4´-dihydroxychalcone DHC and 3,7-dihydroxyflavone DHF) present ...
Spectral analysis allows using the DPPH* UV–Vis assay to estimate antioxidant activity of colored compounds
(Versita, 2020-09)
An accurate measurement of antiradical activity to samples, such as herbal extract and natural or synthetic pure compounds, is essential to estimate its scope as antioxidant, for example, in functional foods. The ...
Amidinoquinoxaline-Based Nitrones as Lipophilic Antioxidants
(MDPI, 2021-08)
The potential of nitrones (N-oxides) as therapeutic antioxidants is due to their ability to counteract oxidative stress, mainly attributed to their action as radical scavengers toward C- and O-centered radicals. Among them, ...
Synthesis of macroporous polymers with radical scavenging properties by immobilization of polyphenolic compounds
(Elsevier Science, 2012-11)
Solid phase radical scavengers have been prepared by the immobilization of antioxidant (AOX) compounds on macroporous polymers. Poly(glycidylmethacrylate- co-trimethylolpropane trimethacrylate) [poly(GMA-TRIM)] and ...
Zuccagnia-type Propolis from Argentina: A potential functional ingredient in food to pathologies associated to metabolic syndrome and oxidative stress
(Wiley Blackwell Publishing, Inc, 2020-08)
The effect of Argentine propolis extracts against enzymes related to metabolic syndrome and oxidative stress, as well as the botanical origin of raw propolis, were studied. Histological and chemical analyses of propolis ...
Microbial functionalization of (–)-ambroxide by filamentous fungi
(Taylor & Francis Ltd, 2011-03)
Biocatalysis is a very useful tool for organic chemists to functionalize organic compounds under working conditions milder than chemical ones. This methodology has special significance since it can be an easy way to introduce ...
