Flavonoids are characterized as the low molecular weight polyphenolic compounds
universally distributed in planta. They are a chemically varied group of secondary …

Flavonoids are a special category of hydroxylated phenolic compounds having an aromatic
ring structure. Quercetin is aspecial subclass of flavonoid. It is a bioactive natural compound …

Flavonoids are plant specialized metabolites that consist of one oxygenated and two
aromatic rings. Different flavonoids are grouped according to the oxidation degree of the …

Plant secondary metabolites, especially flavonoids, are major metabolites widely found in
plants that play several key roles in plant defence and signalling in response to stress …

Whether flavonoids play significant antioxidant roles in plants challenged by photooxidative
stress of different origin has been largely debated over the last few decades. A critical review …

Almost a century after Muriel Wheldale's landmark publication,“The Anthocyanin Pigments of
Plants”(Wheldale, 1916), much about anthocyanin function in plants remains to be …

Stress-responsive dihydroxy B-ring-substituted flavonoids have great potential to inhibit the
generation of reactive oxygen species (ROS) and reduce the levels of ROS once they are …

Abstract Ultraviolet-B (UV-B) radiation has, for many decades now, been widely studied with
respect to its consequences on plant and animal health. Though according to NASA, the …

We discuss on the relative significance of different functional roles potentially served by
flavonoids in photoprotection, with special emphasis to their ability to scavenge reactive …

Phenylpropanoids, particularly flavonoids have been recently suggested as playing primary
antioxidant functions in the responses of plants to a wide range of abiotic stresses …
