Development of a novel dual CD-MEKC system for the systematic flavonoid fingerprinting of Ligaria cuneifolia (R. et P.) Tiegh.—Loranthaceae—extracts
(Wiley VCH Verlag, 2017-05)
The present work deals with the development and validation of a novel dual CD-MEKC system for the systematic flavonoid fingerprinting of Ligaria cuneifolia (R. et P.) Tiegh.—Loranthaceae—extracts. The BGE consisted of 20 ...
Novel synthesis of 3,3′-dihydroxyflavone and apparent formation constants of flavonoid-Ga(III) Complexes
(American Chemical Society, 2010-09)
Flavonoids are a wide variety of polyphenolic compounds. They have many biological properties. They also exhibit a metallic ion complexation capacity, which is important since it has been found that biological properties ...
In vitro antifungal activity of Peltophorum dubium (Spreg.) Taub. extracts against Aspergillus flavus.
(MDPI, 2020-04-02)
Aspergillus flavus is a filamentous, saprophytic fungus, whose colonization occurs mainly in cereal grains and oilseeds once arvested. Under certain conditions, it could produce mycotoxins called aflatoxins, known as ...
Antioxidant capacity of frozen Pleurotus ostreatus during convective drying
(Universidad de Puebla, México, 2016-01)
The influence of drying conditions on antiradical power, total phenols, flavonoids, and surface color in frozen basidiocarps of Pleurotus ostreatus was studied. Drying was carried out in an experimental rig, air velocity ...
Modulation of flavonoid biosynthetic pathway genes and anthocyanins due to virus infection in grapevine (Vitis viniferaL.) leaves
(BMC, 2010-08)
Background: Symptoms of grapevine leafroll disease (GLRD) in red-fruited wine grape (Vitis vinifera L.) cultivars consist of green veins and red and reddish-purple discoloration of inter-veinal areas of leaves. The ...

Como parte de nuestras investigaciones quimiotaxonómicas de plantas argentinas pertenecientes a la familia Asteraceae subfamilia Barnadesioideae, se analiza la presencia de flavonoides en las partes aéreas de Doniophyton ...
Anti-Quorum Sensing Activity of Argentinean Honey and Effect of pH on Main Flavonoids
(Scientific Communications Int Ltd, 2020-04)
In this study, the anti-QS activity of regional floral honey from the southeast region of Argentina was investigated using the bacterial model Chromobacterium violaceum. In addition, the anti-QS activity of quercetin, ...
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 ...
Evaluation of dihydroquercetin-3-O-glucoside from Malbec grapes as copigment of malvidin-3-O-glucoside
(2015-05-15)
Malbec is a wine grape variety of great phenolic potential characterized for its high levels of anthocyanins and dihydroflavonols. To evaluate the possible implication of dihydroflavonols in the expression of red wine color ...
Catechin and quercetin attenuate adipose inflammation in fructose‐fed rats and 3T3‐L1 adipocytes
(Wiley, 2015-04)
Scope
This study evaluated the capacity of dietary catechin (C), quercetin (Q), and the combination of both (CQ), to attenuate adipose inflammation triggered by high fructose (HFr) consumption in rats and by tumor necrosis ...
