Aurones are plant flavonoids that provide yellow color to the flowers of some popular ornamental plants, such as snapdragon and cosmos. [2] Aurones including 4'-chloro-2-hydroxyaurone (C 15 H 11 O 3 Cl) and 4'-chloroaurone (C 15 H 9 O 2 Cl) can also be found in the brown alga Spatoglossum variabile. [3]

Aurones (1, Figure 1) are part of the wide family of polyphenols. More specifically, they may be acknowledged as the lower structural counterparts of the best-known flavones (2, Figure 1), a subclass of flavonoids.

Jan 1, 2021 · Aurones are naturally occurring structural isomerides of flavones that have diverse bioactivities including antiviral, antibacterial, antifungal, anti-inflammatory, antitumor, antimalarial, antioxidant, neuropharmacological activities and so on.

Aurones, 2-benzylidenebenzofuran-3(2H)-ones , also belong to the flavonoid class, being structural isomers of flavones . Even if aurones are less known compared to flavones, research on them has experienced significant development in recent years due …

Aurones are a subclass of active flavonoids characterized with a scaffold of 2-benzylidene-3(2H)-benzofuranone. This type of chemicals are widely distributed in fruit, vegetable and flower, and contribute to human health. In this review, we summarize the …

Aurone is a simplest memebr of the class of aurones that is 1-benzofuran-3(2H)-one in which both hydrogens at position 2 are substituted by a benzylidene group (the Z-isomer). It is a cyclic ketone and a member of aurones.

May 30, 2019 · This article provides generalized and systematic overview of data on the synthesis, stereoisomerism, and reactivity of aurones (2-benzylidenebenzofuran-3(2Н)-ones) published between the years 1910 and 2018.

Dec 1, 2018 · Aurones, (Z)-2-benzylidenebenzofuran-3(2H)-ones, is a class of plant flavonoids that provides the bright yellow color to some important ornamental flowers. The name “aurone” comes from the Latin word aurum (gold) because of its golden yellow color of the pigments in many plants [1] .

Aurones [2-benzylidenebenzofuran-3(2H)-ones] are either natural or synthetic compounds, belonging to the flavonoid family. They are isomeric to flavones and provide a bright yellow color to the plants in which they occur.

Oct 1, 2017 · Aurones, structural isomers of the well-known flavones, are tricyclic flavonoids comprising a benzofuranone core and a phenyl group linked by a carbon-carbon exocyclic double bond (Fig. 1).
