Hesperidin (HDN) is a flavanone
glycoside abundantly found in sweet orange and lemon and is an inexpensive by-product of citrus cultivation (Manach et al.

enriched fraction from bergamot fruit (Citrus bergamia): "In vivo" studies.
Our results indicate that in the future we can use citrus flavanones
to prevent or delay chronic diseases caused by obesity in humans," said Paula S.
Mainly includes: the flavone, flavonol, isoflavones, flavanones
, check ear ketones, isoflavanone, biflavone class.
The term phytoestrogens also includes stilbenes, flavanones
, flavonols and flavones .

medica) by flavones--dosmetin-di-C-glucoside, neodiosmin--and flavanones
Flavonoids are further subclassified in to flavones, flavonols, isoflavones, flavanones
, flavanols, and anthocyanidins [11, 12] (Figure 1).
After the formation of naringenin chalcone flavanones
are produced by another enzyme known as chalcone isomerase CHI (Fig.
After 15 years, the researchers analyzed data on the women's health and diets and found that the women with the highest 20 percent intake of four types of flavonoids--flavones, flavanones
, anthocyanins and flavonols--were more likely to have achieved healthy aging than women with fewer flavonoids in their diets.
Function-structure analysis indicated 1) flavonoids with more free phenolic hydroxyl groups showed relative higher antiplatelet and antiradical activities; 2) substitution of 7-OH of A ring affected antiplatelet capacities of flavanones
apparently; 3) free 3-OH of C ring was important for both the antiplatelet and antiradical activities of flavonol (quercetin) and flavones (rutin isoquercitrin); 4) C ring C2-C3 double bond and B ring 3'-4'orthodihydroxy might be important for its antiradical function.
and phenolic compounds (anthocyanins, flavan-3-ols, proanthocyanidins, flavonols, isoflavons, flavanones
, stilbenes and phenolic acids), which are essential for the human diet [8,18,27,36,44,43,45].
