Flavonoids as Anxiolytics in Animal Tests: Systematic Review, Meta-Analysis, and Bibliometrical Analysis. [PDF]

Phytother Res
ABSTRACT Flavonoids are natural secondary metabolites of plants with a basic composition derived from polyphenols that can produce a plethora of different neurophysiological effects, some of which are relevant to anxiety disorders. As such, many flavonoids have been evaluated in behavioral screens in preclinical research on anxiolytics.

Electrochemistry of Flavonoids

Molecules, 2023
This review presents a description of the available data from the literature on the electrochemical properties of flavonoids. The emphasis has been placed on the mechanism of oxidation processes and an attempt was made to find a general relation between the observed reaction paths and the structure of flavonoids.

Herausforderungen in der Membranentwicklung für die Fruchtsaftklarfiltration – vom Labor in die Produktion Challenges in Membrane Development for Fruit Juice Clarification – from the Lab‐Scale to Production

Chemie Ingenieur Technik, Volume 95, Issue 9, Page 1394-1402, September 2023., 2023
Eine Ultrafiltrations‐Polyethersulfon‐Rohrmembran wird zur Schönung von Apfelsäften eingesetzt. Sie ist jedoch nicht für die Filtration dunkler Fruchtsäfte geeignet, da sie Farbstoffe zurückhält. Um diesen Markt zu erschließen, wird eine Rohrhülsenmembran auf PVDF‐Basis entwickelt.

Photochemistry of Flavonoids [PDF]

Molecules, 2010
Flavonoids and their photochemical transformations play an important role in biological processes in nature. Synthetic photochemistry allows access to molecules that cannot be obtained via more conventional methods. This review covers all published synthetic photochemical transformations of the different classes of flavonoids. It is first comprehensive

Top‐down cascading effects of seed‐feeding beetles and their parasitoids on plants and leaf herbivores

Functional Ecology, Volume 36, Issue 6, Page 1500-1512, June 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract When feeding on a plant, herbivorous insects alter the quality of the plant as a food source. This affects other organisms interacting with the same plant. These so‐called ‘plant‐mediated interactions’ can be altered by parasitoids that attack the herbivores.

Flavonoids: an overview [PDF]

Journal of Nutritional Science, 2016
AbstractFlavonoids, a group of natural substances with variable phenolic structures, are found in fruits, vegetables, grains, bark, roots, stems, flowers, tea and wine. These natural products are well known for their beneficial effects on health and efforts are being made to isolate the ingredients so called flavonoids. Flavonoids are now considered as

Der Einfluss der Ernährung bei entzündlichen Gesichtsdermatosen

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, Volume 20, Issue 2, Page 185-204, February 2022., 2022
Zusammenfassung Der Einfluss von Ernährung auf die Pathogenese und den klinischen Schweregrad entzündlicher Gesichtsdermatosen wird seit Jahren kontrovers diskutiert. Das zunehmende Gesundheitsbewusstsein in unserer Gesellschaft hat zuletzt dazu beigetragen, dass auch die Wahl der Nahrungsmittel von Patienten bewusster getroffen wird und Behandler ...

Detektion und Visualisierung der Pflanzen‐Pathogen‐Response durch Nah‐Infrarot‐fluoreszente Polyphenolsensoren

Angewandte Chemie, Volume 134, Issue 2, January 10, 2022., 2022
Molekulare Sensoren für die Bildgebung von Pflanzenpolyphenolen auf Basis von im Nah‐Infrarot (NIR) fluoreszenten einwandigen Kohlenstoffnanoröhren (SWCNTs) werden vorgestellt. Diese Sensoren untersuchen den Polyphenolgehalt in komplexen biologischen Systemen wie der Rhizosphäre von Pflanzen.
