Flavonoids: an overview [PDF]

open access: yesJournal 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

Electrochemistry of Flavonoids

open access: yesMolecules, 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.

Photochemistry of Flavonoids [PDF]

open access: yesMolecules, 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

Flavonoids and the CNS [PDF]

open access: yesMolecules, 2011
Flavonoids are present in almost all terrestrial plants, where they provide UV-protection and colour. Flavonoids have a fused ring system consisting of an aromatic ring and a benzopyran ring with a phenyl substituent. The flavonoids can be divided into several classes depending on their structure. Flavonoids are present in food and medicinal plants and

Flavonoids and Asthma [PDF]

open access: yesNutrients, 2013
Asthma is a chronic disease, characterized by airway inflammation, airflow limitation, hyper-reactivity and airway remodeling. It is believed that asthma is caused by the interaction between genetic and environmental factors. The prevalence of allergic diseases, including asthma, has increased worldwide during the past two decades. Although the precise

Flavonoids

open access: yes, 2023
Flavonoids are secondary metabolites found in fruit, vegetables, grains, beverages (tea and wine), and also in food by-products. Food by-products have been recognised as significant sources of flavonoids that have been undervalued. Several studies identified that by-products flavonoids content is frequently higher than in the raw source material ...
