While is flavones
bind to oestrogen receptors and exert weak oestrogenic effects, glucosinolates in cruciferous vegetables influence levels of metabolising enzymes that can modulate inflammation and levels of oestrogen, possibly attenuating treatment-related symptoms.
quercifolius aqueous extracts revealed the presence of phenols, flavones
, flavonols, xanthones, catechins, triterpenoids, and tannins.

apigenin and luteolin has been shown to be effective against several tumor cell lines (Lin et al.
Secondly, the expression of enzymes in the phenylpropanoid pathway initially increased and then decreased during floral organ development, peaking during the WB stage that was inconsistent with the accumulation of chlorogenic acid, flavones
and other components.
As a group of compounds, the flavones
are relatively well understood.
A number of flavonoids, comprehending flavones
, flavonols, and several derivatives, which differ in terms of skeleton structure as well as hydroxyl, methoxyl, and other substituted groups, were analyzed (Figure 2).
are found in fresh parsley and thyme, celery, and celery hearts; flavonones, in lemons, oranges, and grapefruit; anthocyanins, in berries, plums, red grapes, and red wine; and flavonols, in yellow onions, kale, leeks, and broccoli.
php) study published in the Journal of Nutrition found that flavones
present in chocolate and other berries cause lower insulin resistance.
They followed 171,940 Nurses' Health Study and Nurses' Health Study II participants to examine associations between intakes of total flavonoids and their subclasses (flavanones, flavonols, anthocyanins, flavan-3-ols, flavones
and polymeric flavonoids) and risk of ovarian cancer by using Cox proportional hazards models.
They found that those who consumed plenty of anthocyanins and flavones
had lower insulin resistance.
A red or orange colour indicates the presence of flavones
aglycones (Shibata's reaction);
Two specific types of flavonoid, flavones
and anthocyanins, were both found to have benefits that could lessen diabetes risk.
Nine different families of polyphenols were analyzed using the shotgun method, including proanthocyanidins, organic acid, flavones
, flavonones, hydrox-ygenzoic acid, hydroxycinnamic acid, oxidation products, anthocyanin-O-flavanol and, finally, anthocyanins.
