Aspalathox has an enriched concentration
of polyphenols, chemical compounds which are known to possess
potent antioxidant (and anti-ageing) properties. The two types
of polyphenols found in Aspalathox are flavanoids click

| Polyphenols click
here to view are a group of chemical compounds
that are widely distributed in nature and the most important
groups of polyphenols in nature are: |
|
1. Flavanoids
2. Esters, glycosides and amides of the hydroxycinnamic acids:
the phenolic acids
3. Gallic acid and its esters
4. Phlorotannins |
|
Of these four groups the flavanoids
click
here to view are considered the most important
from a nutritional perspective. All flavanoids have the same
basic chemical structure, a three-ringed molecule with hydroxyl
(OH) groups attached. The structure shows the tricyclic C6.C3.C6
skeleton. A multitude of other substitutions can occur, giving
rise to many types of flavanoids.
The food flavanoids are further classified as follows: anthocyanidin,
aurones, bioflavanoids, chalcones, dihydrochalcones,
dihydroflavanol, flavanol, flavanones,
flavones, flavanols, isoflavanoids and
proanthocyanidins. click
