hydroxyl radicals through the Fenton reaction. The polyphenols in the extract, particularly flavonoids, possess metal-
chelating properties that can effectively sequester these potentially harmful metal ions.

By binding to these metals, the compounds in Areca Catechu Extract prevent them from participating in redox reactions
that generate free radicals. This chelation mechanism not only directly reduces the production of harmful oxidants but
also indirectly supports the activity of antioxidant enzymes that might otherwise be inhibited by excess free metal ions.

The metal-chelating ability of the extract's components adds another layer to its antioxidant defense strategy,
highlighting the multifaceted nature of its protective mechanisms against oxidative stress.

Modulation of Inflammatory Pathways

Oxidative stress and inflammation are closely interlinked processes, often feeding into each other in a vicious cycle.
Areca Catechu Extract demonstrates the ability to modulate inflammatory pathways, indirectly contributing to its
antioxidant effects.

Certain compounds in the extract, including some alkaloids and polyphenols, have been observed to inhibit pro-
inflammatory enzymes such as cyclooxygenase-2 (COX-2) and lipoxygenase. By dampening these inflammatory
pathways, the extract helps reduce the production of reactive oxygen and nitrogen species that are often byproducts of

inflammatory processes.

Moreover, the extract's components have shown potential in modulating the activity of nuclear factor kappa B (NF-κB),
a key transcription factor involved in inflammation and oxidative stress responses. By influencing these regulatory
pathways, Areca Catechu Extract may help maintain a balanced cellular environment less prone to oxidative damage.

The multifaceted mechanisms through which Areca Catechu Extract combats oxidative stress underscore its potential
as a powerful natural antioxidant. From direct free radical scavenging to enhancing endogenous defenses and
