Phenolic Compounds in Chilean Mistletoe (Quintral, Tristerix tetrandus) Analyzed by UHPLC-Q/Orbitrap/MS/MS and Its Antioxidant Properties
(MDPI, 2016)
Mass spectrometry has become a method of choice to characterize bioactive compounds in biological samples because of its sensitivity and selectivity. Hybrid ultra-HPLC hyphenated with Orbitrap mass analyzer is an innovative ...
Solubilization of phenol derivatives in polymer micelles formed by cationic block copolymer
(Hindawi, 2017)
The aggregation of cationic block copolymers formed by polystyrene (PS) and poly(ethyl-4-vinylpyridine) (PS-b-PE4VP) was studied in aqueous solution. Diblock copolymers of PS and poly(4-vinylpyridine) were synthesized by ...
Antioxidant capacity of abietanes from Sphacele salviae
(2002)
Carnosol 1, rosmanol 2, carnosic acid 3 and 20-deoxocarnosol 4, the main phenolic abietanes present in aerial parts of the Chilean medicinal plant Sphacele salviae were tested for antioxidant activity of measuring the decay ...
Effectiveness of fibers from “Cabernet Sauvignon” (vitis vinifera) pomace as fining agents for red wines
(Wiley, 2018)
Recent findings have highlighted the potential of fibers from grape cell wall material to be fining agents for red wines as alternatives to animal-derived proteins. The affinity of those fibers for grape proanthocyanidins ...
Development of an ingredient containing apple peel, as a source of polyphenols and dietary fiber
(2010)
Apple peel is a waste product from dried apple manufacture. The content of phenolic compounds, dietary fiber, and mineral are higher in apple peel, compared to other edible parts of this fruits. The objective of this study ...
Antioxidant capacity of phenolic compounds in acidic medium: A pyrogallol red-based ORAC (oxygen radical absorbance capacity) assay
(2013)
A novel ORAC (oxygen radical absorbance capacity) assay to assess antioxidant capacity of phenolic compounds in near-gastric conditions (pH 2.0) is presented. AAPH (2,2'-azo-bis(2-amidinopropane)dihydrochloride) was used ...
Controlled water deficit modifies the phenolic composition and sensory properties in cabernet sauvignon wines
(Elsevier, 2018-07-14)
This study investigates the chemical composition and sensory properties of wines from Cabernet Sauvignon vines grown under controlled water deficit in two consecutive seasons. The wines were made from fruit of grapevines ...
Application of Pb–Fe spinel-activated carbon for phenol removal from aqueous solutions: fixed-bed adsorption studies
(Springer Science + Business MediaGermany, 2023)
Increasing heavy metal tolerance by the exogenous application of organic acids
(MDPI, 2022)
Several metals belong to a group of non-biodegradable inorganic constituents that, at low concentrations, play fundamental roles as essential micronutrients for the growth and development of plants. However, in high ...
Phytochemical profiling of coryphantha macromeris (cactaceae) growing in greenhouse conditions using ultra-high-performance liquid chromatography–tandem mass spectrometry
(MDPI AG, 2019)
Chromatographic separation combined with mass spectrometry is a powerful tool for the characterization of plant metabolites because of its high sensitivity and selectivity. In this work, the phytochemical profile of aerial ...
